Abstract:
In this paper the effect of unstable luminescence in nitrides was studied, notably the phenomena of cathodoluminescent intensity rising under stationery electron beam irradiation with typical times of tens up to hundreds of seconds. Long-lasting impact by electron beam leads to changes of cathodoluminescence properties of irradiated area. The changes still remain even after keeping structures at room temperature for several days. Reversibility of this "memory effect" was examined. A model of effect observed was proposed and experimentally verified.

Abstract:
Lanthanum-doped (La:(HfZr)O2) nanometer films of a solid solution of hafnium oxide and zirconium oxide are of great interest for the development of a universal memory that combines an unlimited number of RAM reprogramming cycles and nonvolatile flash memory. This work is devoted to studying the cathodoluminescent properties of La : HfZrO thin films with different contents of lanthanum. It is shown that the cathodoluminescence spectra are dominated by two emission bands with intensity maxima at 2.7 and 2.2 eV. The blue band with an energy of 2.7 eV is due to an oxygen vacancy in La : HfZrO. The study of the influence of the lanthanum impurity and annealing of the samples in argon suggests that the yellow band with the emission maximum at 2.2 eV is related to the oxygen divacancy. Keywords: luminescence, hafnium oxide, zirconium oxide, oxygen vacancy.

Full text
Abstract:
Abstract Quantitative X-ray element maps of cassiterite crystals from four localities show that Ti, Fe, Nb, Ta, and W define oscillatory zonation patterns and that the cathodoluminescent response is due to a complex interplay between Ti activated emission paired with quenching effects from Fe, Nb, Ta, and W. Sector zonation is commonly highlighted by domains of high Fe, incorporated via a substitution mechanism independent of Nb and Ta. A second form of sector zonation is highlighted by distributions of W separate to the Fe-dominant sector zone. Both sector zones show quenched cathodoluminescence and are indistinguishable under routine SEM CL imaging. For cassiterite already high in Fe (and Nb or Ta), such as in pegmatitic or granitic samples, the internal structure of the grain may remain obscured when imaged by cathodoluminescence techniques, regardless of the presence of sector zonation. Careful petrogenetic assessments using a combination of panchromatic and hyperspectral CL, aided by quantitative elemental X-ray mapping, is a prerequisite step to elucidate cassiterite petrogenetic history and properly characterize these grains for in situ microanalysis. The absence of a clear petrogenetic framework may lead to unknowingly poor spot selection during in situ analyses for geochronology and trace element geochemistry, and/or erroneous interpretations of U-Pb and O isotopic data.

Abstract:
Patterns and causes of changes in spectral-kinetic characteristics of the cathodoluminescence in LiF: W crystals are studied under irradiation by nanosecond electron pulses. The contribution of the transformation processes of pre-radiation imperfection and accumulation of color centers to cathodoluminescence distortion is revealed. Optimal operating conditions for LiF:W scintillators are determined. It is found that pre-irradiation of LiF:W with doses of 103–104 Gy causes 1.5–2 fold increase in cathodoluminescence intensity (low dose effect).

Abstract:
AbstractSamples from a traverse across the Blå Måne Sø perthosite unit in the Tugtutôq Central Complex of the Gardar province, South Greenland have been examined for cathodoluminescence characteristics, microporosity and δ18O isotopic values. Reddening of cathodoluminescence colours in alkali feldspars (normally blue) from the unit may be correlated with increased microporosity of the feldspars as determined using scanning electron microscopy. δ18O values of all samples lie within the range of values expected of juvenile fluids, independent of the level of alteration indicated by cathodoluminescence studies.Observations are consistent with previous suggestions that levels of alkali feldspar microporosity and levels of fluid alteration (as determined by cathodoluminescence of alkali feldspars) are related phenomena. Oxygen isotope ratios suggest that the fluid is largely juvenile in origin, with, perhaps, some meteoric (low δ18O) component.

Abstract:
A scanning electron microscope based cathodoluminescence technique utilizing a novel collector system reveals complex internal heterogeneities within granitic quartz grains. The technique overcomes the low intensity and limited variation in cathodoluminescence generated by quartz, which hamper conventional cathodoluminescence analysis. Detailed images of zoning patterns in quartz are comparable to those observed in minerals such as feldspar, and attributed to a combination of progressive growth, boundary layer effects and mineral–melt disequilibria produced during fluctuations in melt composition and temperature during the crystallization interval. We attribute such mineral–melt disequilibria to open system, mixing behaviour in the granite plutons sampled.

Abstract:
AbstractA method for the analysis of cathodoluminescence spectra is described that enables quantitative trace-element-level distributions to be mapped within minerals and materials. Cathodoluminescence intensities for a number of rare earth elements are determined by Gaussian peak fitting, and these intensities show positive correlation with independently measured concentrations down to parts per million levels. The ability to quantify cathodoluminescence spectra provides a powerful tool to determine both trace element abundances and charge state, while major elemental levels can be determined using more traditional X-ray spectrometry. To illustrate the approach, a scheelite from Kalgoorlie, Western Australia, is hyperspectrally mapped and the cathodoluminescence is calibrated against microanalyses collected using a laser ablation inductively coupled plasma mass spectrometer. Trace element maps show micron scale zoning for the rare earth elements Sm3+, Dy3+, Er3+, and Eu3+/Eu2+. The distribution of Eu2+/Eu3+ suggests that both valences of Eu have been preserved in the scheelite since its crystallization 1.63 billion years ago.

Full text
Abstract:
Conodont elements are used as a geochemical archive of seawater. Some compositional features of conodont elements reflect conodont ecology and trophic structure of Palaeozoic pelagic ecosystems. However, the screening of conodont elements prior to geochemical and/or isotopic studies is a real problem. This study evaluates SEM cathodoluminescence (SEM-CL), which is very sensitive to the REE and Mn content of apatite, for the detection of traces of secondary transformation in the composition of conodont bioapatite. The SEM-CL of conodont elements is similar to that of unaltered shark teeth (blue-violet), but differs significantly from that of fossil vertebrate teeth (orange-red). Thermal alteration has little effect on the SEM-CL. Elements with a CAI of 1—1.5 show a redder and more intense CL than elements with a CAI of 5. In the case of corrosion of the conodont element surface in carbonate host rocks, the CL of the outer parts of the conodont element become reddish due to invasion of the carbonate material. Conodont elements from the clay host rock show deep purple SEM-CL. Thus, SEM-CL allows detection of the results of secondary processes in conodont mineralised tissues, including enrichment by REE and/or Mn, corrosion and contamination by carbonate material. This method can be used to screen significantly altered samples prior to chemical and isotopic analyses.

Abstract:
We show that intentional Ga doping of AlN nanowires in the 0.01%–0.5% range leads to the spontaneous formation of nanometric carrier localization centers. Accordingly, for single nanowires, we observed a collection of sharp cathodoluminescence lines in a wavelength range spanning from 220 to 300 nm. From temperature-dependent cathodoluminescence, a ratio between the intensity at room temperature and 5 K of 20–30% is measured. We found that an ensemble of Ga-doped AlN nanowires exhibits a wide-band cathodoluminescence emission, which opens the path to the realization of efficient UV-C light emitting diodes covering a wide part of DNA absorption band.

Abstract:
AbstractHyperspectral cathodoluminescence mapping is used to examine a carbonado diamond. The hyperspectral dataset is examined using a data clustering algorithm to interpret the range of spectral shapes present within the dataset, which are related to defects within the structure of the diamond. The cathodoluminescence response from this particular carbonado diamond can be attributed to a small number of defect types: N-V0, N2V, N3V, a 3.188 eV line, which is attributed to radiation damage, and two broad luminescence bands. Both the N2V and 3.188 eV defects require high-temperature annealing, which has implications for interpreting the thermal history of the diamond. In addition, bright halos observed within the diamond cathodoluminescence, from alpha decay radiation damage, can be attributed to the decay of 238U.

AbstractWe report a systematic spectroscopical investigation of three plagioclase particles (RB-QD04-0022, RA-QD02-0025-01, and RA-QD02-0025-02) returned by the Hayabusa spacecraft from the asteroid Itokawa, by means of scanning electron microscopy, cathodoluminescence microscopy/spectroscopy, and micro-Raman spectroscopy. The cathodoluminescence properties are used to evaluate the crystallization effects and the degree of space weathering processes, especially the shock-wave history of Itokawa. They provide new insights regarding spectral changes of asteroidal bodies due to space weathering processes. The cathodoluminescence spectra of the plagioclase particles from Itokawa show a defect-related broad band centered at around 450 nm, with a shoulder peak at 425 nm in the blue region, but there are no Mn- or Fe-related emission peaks. The absence of these crystal field-related activators indicates that the plagioclase was formed during thermal metamorphism at subsolidus temperature and extreme low oxygen fugacity. Luminescence characteristics of the selected samples do not show any signatures of the shock-induced microstructures or amorphization, indicating that these plagioclase samples suffered no (or low-shock pressure regime) shock metamorphism. Cathodoluminescence can play a key role as a powerful tool to determine mineralogy of fine-grained astromaterials.

Abstract:
In the present study, the concentration series of MgAl2O4:Ce3+ ceramics have been fabricated by the Spark Plasma Sintering (SPS) method. Cerium-doping concentration was varied within a range of 0.1–5 wt.%. The prepared ceramics have been tested using the various experimental techniques: X-ray diffraction (XRD), scanning electron microscopy, as well as optical and cathodoluminescence spectroscopy. According to XRD, all synthesized samples are biphasic with structural impurities. The cerium ion concentration effect on the cathodoluminescent characteristics of MgAl2O4:Ce3+ ceramics has been studied in terms of emission intensity and decay time. Before annealing the concentration, quenching is observed. The optimal doping Ce3+ concentration was determined to be 5 wt.% after temperature annealing at 1300 °C. The successfully prepared spinel ceramics could be potentially applying for high-energy electrons detection.

Abstract:
Lanthanum-doped (La:(HfZr)O2) nanometer films of a solid solution of hafnium oxide and zirconium oxide are of great interest for the development of a universal memory that combines an unlimited number of RAM reprogramming cycles and nonvolatile flash memory. This work is devoted to studying the cathodoluminescent properties of La:HfZrO thin films with different contents of lanthanum. It is shown that the cathodoluminescence spectra are dominated by two emission bands with intensity maxima at 2.7 and 2.2 eV. The blue band with an energy of 2.7 eV is due to an oxygen vacancy in La:HfZrO. The study of the influence of the lanthanum impurity and annealing of the samples in argon suggests that the yellow band with the emission maximum at 2.2 eV is related to the oxygen divacancy.

Abstract:
Two-dimensional and three-dimensional mathematical models of diffusion and cathodoluminescence of excitons in single-crystal gallium nitride excited by a pulsating sharply focused electron beam in a homogeneous semiconductor material are compared. The correctness of these models has been carried out, estimates have been obtained to evaluate the effect of errors in the initial data on the distribution of the diffusing excitons and the cathodoluminescence intensity.

Abstract:
The spectral and amplitude-time characteristics of the emission of polymethyl methacrylate upon excitation by electron beams with electron energies up to 300 and 450 keV are studied. Vavilov-Cherenkov radiation and cathodoluminescence pulses were recorded with a subnanosecond time resolution. It is shown that the intensity of pulsed cathodoluminescence radiation in the visible and near ultraviolet spectral regions at electron energies of hundreds of keV exceeds the intensity of Vavilov-Cherenkov radiation.
