The UV absorption spectra of monolayers of 12-(9-anthrylcarbonyloxy)octadecanoic acid (12-AS), 2 -(9-anthrylcarbonyloxy)hexadecanoic acid ( 2 -AP), and 2 -octadecylamino- 6 -naphthalenesulfonic acid (ONS ...
The absorption and fluorescence spectra provide direct information about the energy levels of the ions in a crystal. Alternatively, the ions may be regarded as probes measuring the crystalline field ...
polarity . The absorption and fluorescence spectra of 1-methyl-4-( 2 -pyren-1-yl-vinyl)-pyridinium iodide show a dramatic dependence on solvent polarities in the high- polar range. It exhibits two absorption ...
were evaluated for an azo- ( 2 ) and a bisazo- compound ( 6 ). All azo-5-pyrazolone compounds showed fluorescence properties and the solvents with different polarities gave rise to shifts in the absorption ...
An Ho3+-doped YAlO3 (Ho:YAP) single crystal has been grown by the Czochralski technique. The polarized absorption spectra , polarized fluorescence spectra and fluorescence decay curve of the crystal ...
in various ratios of water to propan- 2 -ol. Panel A shows the fluorescence emission spectra after excitation at the main maximum of the absorption spectra (as presented in Fig 6 , Panel A), i.e. at approx. 300 ...
The excited‐state intramolecular proton transfer (ESIPT) process of 6 ‐amino‐ 2 ‐( 2 ′‐hydroxyphenyl) benzoxazole (6A‐HBO) was investigated using density functional theory and time‐dependent density ...
and luminescence spectra of the five indicators coumarin 153, coumarin 314, coronene, 4-dicyanomethylene- 2 -methyl- 6 -[4-(dimethylamino)styryl]-4H-pyran (DCM), and 3-aminophthalimide in solvents of different polarity ...
A Pr3+:NaGd(MoO4) 2 single crystal has been grown by the Czochralski method. The polarized absorption spectra , polarized fluorescence spectra , and fluorescence decay curves of the crystal were ...
technique. Polarized absorption and fluorescence spectra as well as fluorescence decay kinetics had been measured for these crystals, doped with Yb 3+ ions. Gain cross-section for different population ...
