Abstract
Emission decay curves and time-resolved emission spectra have been measured as a function of temperature for 10 to 50 K in crystals of the one-dimensional salt BaPt(CN)4·4H2O, both undoped and with 1 : 650 and 1 : 65 doping by Ni(CN)2– 4. The decay curves of the lowest-frequency emission (18 400 cm–1 at 10 K) are least-squares fitted to obtain the variation of the longest-lifetime component with temperature. The ratio of the intensities of the 18 400 and 20 100 cm–1 bands in the short (50 ns) time-resolved emission spectra varies with temperature and doping level. The results are interpreted with a three-level model, including radiationless passage from the lowest excited state of Pt(CN)2– 4 to Ni(CN)2– 4.Keywords
