Popis: | Room temperature and low temperature optical absorption measurements are performed on Nd2O2S in crystal and powder form. The experimental oscillator strengths are deduced and compared with calculations at 8 and 300 K including the contribution of Judd-Ofelt and Jorgensen-Judd mechanisms. The global oscillator strengths are satisfactorily reproduced by considering the sum of both contributions but the relative intensities of the strong transitions are best reproduced by the Jorgensen-Judd mechanism alone. |
