The Investigation of Fine Structure of Spin-admitted Spectrum in GaP:V^(3+)

在GaP :V3 + 晶体中 ,对 3 A2  3 T1(F) ,3 A2  3 T1(P)以及3 A2  3 T2 (F) 3组自旋允许跃迁均已在实验中测得了它们的精细结构 .同时考虑静电、晶场和自旋 轨道耦合作用 ,计算了GaP :V3 + 的旋轨耦合分裂 ,理论计算与实验符合很好 .此外 ,还对这 3组自旋允许跃迁的精细结构进行了识别 ,结果表明 ,3 A2 3 T1(P)跃迁的 3条 13874,13890和 13946cm-1分别对应E′ T′2 ,T1′ 和A′;3 A2  3 T1(F)跃迁的 3条锐线86 97,8711和 876 0cm-1分别对应A′ T′2 ,E′ 和T1′;而3 A2  3 T2 (F)跃迁的 3条锐线 6 382 ,6 397和6 399cm-1则分别对应T′2 ,T1′ 和E′.

WT5”BZ]In GaP:V 3+ crystal,the fine structure of spectrum had been investigated by experiment for three spin admitted transition: 3A 2 3T 1(P), 3A 2 3T 1(F) and 3A 2 3T 2(F). This paper calculates the fine structure of GaP:V 3+ crystal by considering electrostatic, crystal field and spin orbit coupling interactions. The theoretical results are in good agreement with the experiments. The assignment for the fine structure of spectrum is obtained. The result shows that, the three sharp spectral lines 13 874,13 890 and 13 946 cm -1 are corresponding with E ′T ′ 2,T 1 ′ and A ′ respectral in  3A 2 3T 1(P)transition, the three sharp spectral lines 8 697,8 711 and 8 760 cm -1 are corresponding with A ′T ′ 2,E ′ and T 1 ′ respectively in 3A 2 3T 2(F) transition, the three sharp lines 6 382,6 397 and 6 399 cm -1 are corresponding with T ′ 2,T 1 ′ and E ′ respectively in  3A 2 3T 2(F) transition.
