本文研究了磷酸盐、氟磷酸盐和氟化物玻璃中Cr3+的顺磁共振(以下简称ESR),从自旋哈密顿出发计算了Cr3+的有效g因子,指出低场谱线主要起源于两个Kramers双重态之间的跃迁,确定了自旋哈密顿参数:D=0.15—0.4cm-1,E/D=0.15—0.3,零场分裂为0.3—0.8cm-1,本文还报道了磷酸盐玻璃中Mo3+的ESR。The ESR of Cr3+ in phosphate, fluorophosphate and fluoride glasses has been studied. The effective g factors of Cr3+ have been calculated with the Spin-Hamil-tonian. It is pointed out that the low-field spectra resulted mainly from transition between two Kramers doublets. Hamiltonian parameters have been determined: D=0.15-0.4 cm-1, E/D=0.15-0.3; zero-field splitting: 0.3-0.8 cm-1. In this paper, the ESR of Mo3+ ion in phosphate glass is also reported.
