Abstract
The absorption and emission spectra of ZnS:Tm3+ and Ho3+ were observed at 4.2°, 77°, and 290°K between 3400 and 9000 Å by using a high-dispersion spectrograph. The L—S coupling terms of Tm3+ and Ho3+ were determined and the spin—orbit interaction term ζ and the Slater integral F2 were estimated for Tm to be 2702 and 440 cm—1, respectively. Also the crystal field splitting terms and the pressure dependence of absorption and emission are discussed in this paper.Keywords
