Nanocrystalline TiO2 thin filmswere prepared by spin coating on covered glass substrates with an indium tin oxide (ITO) layer. The structural, electrochromic and optical properties of the films were investigated. The films are crystallized predominan

The electrical characteristics of Al/chlorophyll a/Ag (Al/Chl a/Ag) structures, prepared by electrodeposition of chlorophyll a onto vacuum evaporated aluminum and followed by evaporation of silver (Ag) top electrode, are presented. It was found that

A comparative luminescence study of 5 related 2-aminoazines indicates that there is a dependence of emission polarization and other photophysical parameters upon the extent of charge transfer in the lowest excited singlet and triplet states. The phos

Capacitance measurements of the cells, obtained by sandwiching mixed monolayers of chlorophylla and canthaxanthin between Al and Ag electrodes, have been carried out at various frequencies in the dark and under illumination. The results show that at

Fluorescence and phosphorescence results for 4-phenylpyridine are found to be consistent with predictions from CNDO/S calculations. The latter readily account for the acidic medium needed to detect fluorescence, which involves the inversion of n,π a

Clusters of C60-aniline dyads are deposited as thin films on nanostructured SnO2 electrodes under the influence of an electric field. At low applied DC voltage (5 V) the clusters in toluene/acetonitrile (1:3) mixed solvent grow in size (from 160 nm t

A phosphorescence emission and polarization study of 4-hydroxypyridine has been performed in EPA and in alkaline EPA. In contrast to the lack of luminescence from pyridine, 4-hydroxypyridine phosphoresces with φp = 0.40 (77°K) in EPA and τp = 0.27

Laser excitation at 457.9 and 514.5 nm of a frozen solution of chlorophyll a in n -octane produces two fluorescence peak maxima at 2 K that may be assigned to two distinct monomeric chlorophyll species. Utilizing zero-field fluorescence-detected magn

Phosphorescence quantum yields and lifetimes of 2‐, 3‐, and 4‐ hydroxypyridine and 2‐methoxypyridine have been measured at 77 ° K in EPA and alkaline EPA using 285 and 254 nm excitation. The phosphorescence polarization is negative with the
