The identification of biological aerosols is a subject of worldwide interest because of the potential for biological terrorism and the increase in public health emergencies. Laser-induced fluorescence is widely used to investigate the fluorescence properties of biomolecules and spores in solution; however, data on the fluorescence properties of the aerosolized forms are lacking. In this study, we report the fluorescence properties of tryptophan, serotonin, tyrosine, vitamin B6, and Bacillus thuringiensis and Bacillus subtilis spores in solution and aerosol form.

Abstract Absorption spectra and fluorescence properties of 2,3-dihydro-4(1 H)-quinolinone derivatives were studied at room temperature in different solvents. It has been found that the fluorescence quantum yields and fluorescence decay times strongly depend on the molecular structure and solvent polarity. The character and the energy of excited states were determined by PPP and CNDO/S quantum-chemical calculations.

New indeno[1,2-c]pyran-3-ones bearing different substituents at the pyran moiety were synthesized and their photophysical properties were investigated. In solution all compounds were found to be blue emitters and the trans isomers exhibited significantly higher fluorescence quantum yields (relative to 9,10-diphenylanthracene) as compared to the corresponding cis isomers. The solid-state fluorescence spectra revealed an important red shift of λmax due to intermolecular interactions in the lattice, along with an emission-band broadening, as compared to the solution fluorescence spectra.

The effect of the chemical structure of polymethine dyes on their spectral-luminescent and photovoltaic properties has been studied.

During the adsorption of dyes on the surface of titanium dioxide, a shift of their spectra to the red wavelength region was recorded with a simultaneous broadening of the bands caused by dye aggregation on the semiconductor surface.

The long-wave excitation peak practically coincides with the long-wave absorption peak of these substances, covering the region from 284 to 293 nm, the maximum emission being in the range 320-332 nm. With alkaloids having a number of conjugated rings, both excitation and emission were observed at higher wavelengths. Only protoberberine alkaloids behaved as hydrophobic probes, i.e. t

The synthesis, fluorescence properties and singlet oxygen generation capability of germanium tetrabenzotriazacorrole (LGeTBC), germanium phthalocyanine (Cl[Formula: see text]GePc) and their derivatives are described. Measurements include UV-vis absorption spectra, fluorescence emission spectra, fluorescence quantum yields fluorescence lifetimes, and singlet delta oxygen quantum yields. LGeTBC and its derivatives exhibit quite different spectral and fluorescence properties from their phthalocyanine precursor. Both LGeTBC and Cl[Formula: see text]GePc show high singlet delta oxygen quantum yield

Fluorescence bioimaging is considered an indispensable technique in biological research due to its high sensitivity, excellent spatial and temporal resolution, non-invasiveness, rapid and real-time responsiveness, as well as its ease of accessibility. Among these, fluorescence probes play a pivotal role in fluorescence imaging technology thanks to their strong specificity, high sensitivity, rapid response, and straightforward implementation. Aggregation-Induced Emission (AIE) molecules exhibit a unique phenomenon: they emit weak or no fluorescence when dissolved in a solution but become highly

The absorption spectra, fluorescence spectra, fluorescence lifetimes, fluorescence quenching, phosphorescence spectra, phosphorescence lifetimes, and picosecond transient absorption spectra of several purinyl-pyridinium salts have been measured in several solvents at room temperature and in ethanol glasses at 77 K. It is concluded that the previously observed photochemical transformation of N-[9-(2′,3′,5′-tri-O-acetyl-β-D-ribofuranosyl)purin-6-yl]pyridinium chloride 1 into the highly fluorescent tri-O-acetylluminarosine 6 occurs via an excited triplet state. It is also shown that intersystem c

A new photochromic diarylethene compound 1,2-(2-ethyl-3-benzofuryl) perfluorocyclopentene was synthesized. And its properties including photochromism, fluorescence both in hexane and solid films were studied. And its absorption maxima were observed at 489 nm in hexane and at 499 nm in PMMA films, respectively, upon irradiation with 313 nm UV light. The fluorescence intensity of diarylethene decreased upon irradiation with 313 nm UV light. And the fluorescence modulation efficiency was better in PMMA films than that in hexane.
