Abstract:
A series of α-cyanostilbene derivatives with aggregation-induced enhanced emission （AIEE） was obtained. All the compounds were characterized by UV−vis spectroscopy, fluorescence and nuclear magnetic resonance. These compounds exhibited blue, green and yellow color emission in solid state but non-fluorescent in dilute solutions. The electronic characteristics were examined by GAMESS Interface software package. The results indicate that the luminescence properties are affected by the substituents.

Abstract:
The ability to manipulate the luminescent color, intensity and long lifetime of nanophosphors is important for anti-counterfeiting applications. Unfortunately, persistent luminescence materials with multimode luminescent features have rarely been reported, even though they are expected to be highly desirable in sophisticated anti-counterfeiting. Here, the luminescence properties of Zn3Ga2GeO8:Mn phosphors were tuned by using different preparation approaches, including a hydrothermal method and solid-state reaction approach combining with non-equivalent ion doping strategy. As a result, Mn-activated Zn3Ga2GeO8 phosphors synthesized by a hydrothermal method demonstrate an enhanced red photoluminescence at 701 nm and a strong green luminescence with persistent luminescence and photostimulated luminescence at 540 nm. While Mn-activated Zn3Ga2GeO8 phosphors synthesized by solid-state reactions combined with a hetero-valent doping approach only exhibit an enhanced single-band red emission. Keeping the synthetic method unchanged, the substitution of hetero-valent dopant ion Li+ into different sites is valid for spectral fine-tuning. A spectral tuning mechanism is also proposed. Mn-activated Zn3Ga2GeO8 phosphors synthesized by a hydrothermal approach with multimodal luminescence is especially suitable for multiple anti-counterfeiting, multicolor display and other potential applications.

Abstract:
Ternary layered gadolinium-europium-terbium basic chlorides were synthesised using a facile hydrothermal-microwave technique. A continuous series of solid solutions was obtained in a full range of rare earth concentrations. To sensitise the luminescence of Eu3+ and Tb3+, a 4-sulfobenzoate anion was intercalated in the ternary layered rare earth hydroxides using one of two methods—a high-temperature ion exchange or a single-stage synthesis. The luminescent colour of the materials was governed by the gadolinium content: at low and medium gadolinium concentrations (0–70%), layered Gd-Eu-Tb basic sulfobenzoate exhibited a bright red europium luminescence; at high gadolinium content (70–90%), a bright green terbium luminescence was observed. The colour coordinates of layered Gd-Eu-Tb basic sulfobenzoate luminescence depended on the temperature in the physiological range (20–50 °C). The relative thermal sensitivity of the obtained materials was up to 2.9%·K−1.

Abstract:
Existing calcium gallate CaGa2O4 based luminescent materials radiating in visible IR region have been reviewed. IR luminophores have been studied but slightly but their practical implementation is of interest. CaGa2O4 specimens activated with Yb3+ rare-earth ions have been synthesized using the solid-state method. The structure and luminescent properties of CaGa2O4 : Yb3+ have been studied. CaGa2O4 : Yb3+ excitation with 940 and 980 nm radiation generates luminescence in the 980–1100 nm region. Data on the electron level structure in Yb3+ ions suggest that the excitation and luminescence occur directly in the Yb3+ ions with only a passive role of the base lattice. The luminescence spectra contain three peaks at 993, 1025 and 1080 nm. These luminescence peaks are caused by electron optical transitions from excited to main state in Yb3+ ions. 993 nm band luminescence intensity has been studied as a function of Yb3+ activator ions concentration. Introduction of Na+ ions into the luminophore increases IR luminescence intensity. Optimum (Ca1-x-yYbxNay)Ga2O4 luminophore composition has been suggested at which the 993 nm luminescence intensity is the highest.

Transparent luminescent TiO2/polymer nanocomposites were obtained through the combined use of copolymerization of a novel titanium ion containing monomer with a liquidsolid reaction. The titanium ions are covalently introduced into polymer chains and transformed into TiO2 nanocrystals directly in the solid-state polymer matrices. That allows the generation of high-quality anatase TiO2 nanocrystals with a narrow size distribution in the polymer matrices. The luminescence of the TiO2 nanocrystals is dominated by band-edge luminescence at room temperature.

Abstract:
Luminescent pigments are able to absorb the energy of natural or artificial light sources and release it in the form of a visible glow in the dark. By chemical nature, phosphors are divided into inorganic and organic. Unlike inorganic luminophors, which glow only in the solid state, organic luminophors, in most cases, luminesce in various aggregate states. This difference is due to the fact that the glow is associated with a certain structure of the crystal lattice, which includes activating additives. After the destruction of the crystal lattice, luminescence disappears. In the case of organic luminophors, individual molecules luminesce. It is well known that the quantum yield of fluorescence of organic chromophores usually decreases in the solid state, although they have a high quantum yield of luminescence in solution.

Abstract:
Abstract The transition metal Mn2+ ions doped materials have been widely reported for the luminescent properties for its broad emission band from green to red due to the spin-forbidden 4T1→6A1 transitions. To investigate the luminescent properties of Mn2+ ions in cuspidine glass, the 3CaO-CaF2-2SiO2 glasses doped with different Mn2+ concentration were prepared with traditional melt-quenching method. The luminescence emission spectra, excitation spectra and luminescence decay curves were recorded and analyzed. The tunable broadband emission from orange to red was obtained. The luminescence intensity and lifetime of Mn2+: 4T1 level showed different quenching points with the increasing of Mn2+ concentration. All these results indicate that Mn2+ doped 3CaO-CaF2-2SiO2 glass could be applied as light conversion material for solid-state lighting applications.

Abstract:
Luminescent phenomena have fascinated mankind since the earliest times. The light from the aurora borealis, glow worms, luminescent wood, rotting fish and meat are all examples of naturally occurring luminescence. E. Newton Harvey’s 770 page volume “A History of Luminescence: From the Earliest Times until 1900” is a classic which narrates interesting stories from ancient cultures to modern times. The earliest written account of a solid state luminescent material comes from a Chinese text published in the Song dynasty (960–1279 A.D.). The Buddhist sacred jewel, called "hashi-no-tama" in Japan, is alleged to be self-luminous and to shed a brilliant light on its surroundings. In the Svetasvatara Upanishad, probably recorded at some time before the sixth century BC, we find a mention of fire-flies as one of the manifestations of Brahma.

Abstract:
The Yb3+ and Er3+ co-doped yttrium molybdenum oxide upconversion phosphors were prepared by the solid state combustion method using urea as fuel at ignition temperature of 550 °C. The upconversion phosphors were characterized by X-ray diffraction (XRD), scanning electronic microscope (SEM), and photoluminescence spectra. XRD results revealed the samples were pure monoclinic Y2Mo4O15 phases when the sintering temperature was 700 °C. SEM micrographs illustrated particle size distribution was almost uniform with an average particle diameter of about 0.5–1.0 m. The obtained Y2Mo4O15:Yb3+, Er3+ presents bright and pure green upconversion luminescence during daylight pumping under 980 nm LD. According to the analysis of upconversion luminescent mechanism, the cross relaxation processes of Er3+ ions restrained the electron population of red emission energy level, which not only increased the green light upconversion emissions fluorescent branching ratio (IG:IR = 153:1) but also enhanced the efficiency and purity of green light emissions.

Abstract:
Owing to the unique 4f-5d transition, Eu2+ is one of the most commonly used activators in luminescent materials for phosphor-converted light-emitting diodes (pc-LEDs), and Eu2+-doped phosphors exhibit outstanding luminescence properties, including multi-color emission, adjustable bandwidth, excellent thermal stability as well as high luminescence efficiency. These attributes motivate scientists to find Eu2+ doped phosphors that can practically meet the various LED application requirements. In this talk, I will summrize our recent progresses to manipulate Eu2+ emission exhibiting red and near-infrared emissions under blue light excitation. One can expect and further adopt proper structural engineering strategies to tune the Eu2+ luminescence. Moreover, the state-of-the-art LED application including solid-state lighting and near infrared night-vision technologies will be also introduced based on these Eu2+ doped phosphors. We hope this talk will be helpful for controlling the photoluminescence by theory-structure-property relationships and guide scientists discover the next generation of Eu2+ doped phosphors for emerging applications.

Abstract:
Temperature was varied over a wide range to determine its effect on the luminescence properties of deuterated phenanthrene and phenanthrene adsorbed on a number of solid matrices. Not only were insights into the effects of temperature and solid matrices on the luminescence properties acquired but also the deuterium isotope effect revealed unique information about the role played by the solid matrix in the luminescence of the model compounds. In addition, comparisons of nonradiative rate constants and the efficiencies of intersystem crossing revealed important differences among the solid matrices in altering these parameters. The perdeuterated phenanthrene and phenanthrene proved to be useful probes for investigating the effects of solid matrices on the excited triplet state of phosphors because the excited singlet state of the lumiphor was affected very little by the solid matrices, and the rate constants of phosphorescence for the two phosphors are essentially the same.

Abstract:
As part of an ongoing study of the electronic interactions between solute and solvent molecules, a method for X-ray excited optical luminescence (XEOL) analysis of aqueous solutions was developed at the double-crystal monochromator beamline (DCM) of the Canadian Synchrotron Radiation Facility (CSRF). It was tested using a series of solutions containing lanthanide ions. The samples were contained in a sample holder for liquids with a 3 μm Mylar window separating them from the vacuum (≤3 × 10−6 torr, 1 torr = 133.3224 Pa) in the solid state absorption chamber of the DCM beamline. Terbium, samarium, and dysprosium have 4 intense and narrow luminescence peaks between 450 and 700 nm, well separated from the luminescence peak of the Mylar window between 300 and 425 nm. The intensity of the rare earth (RE3+) luminescence peaks was lower for the solutions than for solid RECl3·6H2O. In part, this was caused by the lower RE3+ concentration in the solutions than in the solid. In addition, the solvent (water) acts as a quencher. The disorder and the molecular motion in the solution increase the availability of nonradiative de-excitation pathways. A high concentration of SO42− in the solution enhanced the luminescence intensity, probably by inhibiting some nonradiative de-excitation pathways. This study has shown that it is in principle possible to investigate the luminescence of aqueous solutions with XEOL spectroscopy. Furthermore, it is possible to use this technique as a quantitative analytical tool for concentrated luminescent solutions and to study the shielding effects of anions in the solution that increase the luminescence intensity.

Abstract:
Eu3+-doped SmBa3B9O18 luminescent materials were synthesized by high temperature solid state reactions. The structure and photoluminescence properties of Sm(1−x)EuxBa3B9O18 (x = 0.2, 0.4, and 0.6) were investigated by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, and photoluminescence spectra. The results show that doping of Eu3+ ions does not change the structure of SmBa3B9O18. The luminescence is mainly the characteristic Eu3+ ion luminescence. No concentration quenching processes occur with the increment of Eu3+ concentration. The work implies that SmBa3B9O18 is a potential host material and europium-doped SmBa3B9O18 may find application in display and optical devices.

Abstract:
A novel sensor for quantifying molecular O2 based entirely on solid-state electronics is presented. The sensor is based on the luminescence quenching of tris(4,7-diphenyl-1, 10-phenanthroline)ruthenium(II) ([Ru(dpp)3]2+) by molecular O2. The sensor involves immobilizing the ruthenium complex within a porous sol-gel-processed glass film and casting this film directly onto the surface of a blue quantum-well light-emitting diode (LED). The ruthenium complex is excited by the LED, the [Ru(dpp)3]2+ emission is filtered from the excitation with a low-cost acrylic color filter, and the emission is detected with an inexpensive silicon photodiode. The sensor response to gaseous O2 and dissolved O2 in water is presented. The sensor exhibits fast response times and good reversibility, and detection limits are 0.5%, 0.02%, and 110 ppb, respectively, for O2 in the gaseous (linear Stern–Vobner and multi-site Stern–Volmer analysis) and aqueous phase. This sensor provides a cost-effective alternative to traditional electrochemical-based O2 sensing and also provides a platform for other optically based sensors.

Abstract:
The Europium(III) ternary complexes Eu(BID)3(PHEN) and Eu(MBID)3(PHEN) (BID – 2-benzoyl-1,3-indandione, MBID - 2-(4-methylbenzoyl)-1,3-indandione and PHEN – 1,10-Phenantroline) were synthesized, characterized and incorporated into poly methyl methacrylate (PMMA) and poly-N-vinylcarbazole (PVK) matrixes. Emission properties in solid-state and polymer films were investigated through excitation spectra, emission spectra and absolute photoluminescence quantum yields (PLQY). Both complexes in their solid-state and films exhibited red-light luminescence with narrow bands corresponding to Eu(III) ion emission. In solid-state complexes were characterized with PLQY of 6% and 10%, in PVK matrixes quantum yield dropped down to 4%, however, in PMMA films exhibited similar luminescence PLQY than in solid-state.

Abstract:
The organic luminophores consist of a diverse array of compounds exhibiting well understood conventional emission behaviour. Though their solution-state luminescence is well established, few luminophores are capable of exhibiting bright solid-state emission. Therefore, various theories to afford high solid-state emission from organic compounds, are currently under development. The formation of cross aggregate or X-aggregate is a novel way, where the energy-consuming pi-pi stacking of planar luminophores are disrupted using steric requirements. In this review, the recent reports on the X-aggregates along with their luminescence mechanism and effect of packing on emission behaviour are discussed.

Abstract:
The pure phase red phosphor yttrium borate doped with Eu3+was prepared by a new solid state reaction named high temperature ball milling method. The phosphor was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and luminescence spectra. The results show that the single phase YBO3:Eu3+phosphor was obtained at 600°C, which is obviously decreased in contrast to conventional solid state reaction method. The particles are approximately nanometer size with narrow distribution range and spherical morphology. In emission spectra, the strongest peak at 597nm is due to the transition5D0→7F1 of Eu3+ions under 394nm monitoring wavelength. The luminescent properties of YBO3:Eu3+phosphor with 25 mol% doping concentration of Eu3+is optimal.

Abstract:
A subset of solid state materials have long been used as integrating dosimeters because they store energy deposited as a result of their interactions with ionizing radiation and then, when stimulated appropriately, release a proportionate amount of visible or near-visible light. During the 1960s, thermoluminescent dosimeters (TLDs), for which heat is used to extract the stored dosimetric signal, began to replace the photographic film as occupational dosimeters of record and for medical dosimetry. At the end of the twentieth century, a viable optically stimulated luminescent (OSL) material was developed which is now gaining in popularity as both an occupational and medical dosimeter. This paper reviews the related stored luminescence processes, presenting a simple conceptual model for optical absorption transitions in OSL materials along with a basic mathematical model for delayed luminescence. The approaches for extracting signal from the OSLs are enumerated.

Abstract:
SrY2O4:Eu3+ phosphors were synthesized by both the solid-state reaction method and the sol-gel method, and their photoluminescence in vacuum ultraviolet (VUV) and the ultraviolet (UV) region were evaluated. The excitation spectra of SrY2O4:Eu3+ phosphors prepared by solid-state reaction show another excitation band centered at 324 nm except for the charge-transfer bands (CTB) of Eu3+ when monitored at 610 nm, and a blue emission band around 406 nm is observed when excited at 324 nm, which could be associated with defects. Both the excitation and emission bands mentioned above disappear when the samples were prepared by the sol-gel method. SrY1.98O4:0.02Eu3+ phosphors synthesized by the sol-gel method exhibit a higher emission intensity under 147 nm excitation compared with solid-state reaction technology. The main reason could be that the samples prepared by the solution-based route have more regular and uniform morphologies.
