摘要：

The quantum yields of luminescence and 2E lifetimes have been determined as a function of temperature for Cr3+ in the crystalline hosts, K3Co(CN)6, NaMgAl(C2O4) 3·9H2O, C(NH2)3Al(SO 4)2·6H2O(GASH), C(NH2) 3Al(S04)2·6D2O(GASD), AlCl3·6D2O, and AlCl3·6D 2O. The effect of structure and environment on the nonradiative transitions has been assessed. For a given complex, the probability of the nonradiative 2E→4 A3 transition may or may not depend upon environment. In all cases, only phosphorescence is observed at low temperatures, but upon warming, the aquo complexes fluoresce. Depopulation via 4T2 is the dominant thermal relaxation process of 2E.
