Abstract
Strong sharp-line luminescence has been observed for Os4+(5d4) as an impurity in single cubic crystals of Cs2ZrCl6 and K2PtCl6 at low temperatures. For Os4+ in Cs2ZrCl6, sharp-line luminescence within the t 2g 4 configuration, is observed from the Г1(1 A 1g ) excited electronic state at 17069 cm-1 to the four spin-orbit components of the 3 T 1g ground electronic state at 0, 2777, 4873, and 4972 cm-1. For Os4+ in K2PtCl6, a similar set of transitions is observed. Excitation of the sample was carried out by use of a krypton laser at 568·2 nm and with a xenon or mercury lamp. The detailed vibrational structure can be interpreted from a phonon density-of-states calculation.This publication has 19 references indexed in Scilit:
