Phosphorescence decay times of thiocyanate complexes of chromium (III) in DMSO

Abstract

We report the phosphorescence spectra and decay times of chromium (III) solvo-complexes of the [Cr(NCS) 6− n (DMSO) n ] n− 3 type. It is shown that the decay times are linked with the number of solvated molecules. The rate of phosphorescence decay of mixed solvo-complexes depends mainly on the maximum vibrational frequency and number of coordinated molecules.
