GdP5O14:Sm3+,Pr3+晶体生长,光谱和离子间的能量传递
摘要:
Sm3+[1]和Pr3+[2]离子在不同基质中的发光及边带振动已有详细的报道.目前,考查Gd3+、Sm3+和Pr3+离子发光及离子间的能量转移是发光和激光材料学科中研究的热点之一.轻稀土五磷酸盐中,稀土离子处在隔离的多面体中,离子间的相互作用减弱,有好的发光性质和小的浓度猝灭效应,即使在化学计量比的NdPP和PrPP晶体中仍得到激光输出.

On the Growth, Spectrum and Energy Transfer Between Sm3+ and Pr3+ Ions of GdP5O14:Sm3+,Pr3+ Single Crytal
Abstract:
The single crystal of GdP5O14:Sm3+,Pr3+ (GdPP:Sm,Pr) was grown by the hydrothermal method. The crystal belongs to the monoclinic space group P21/C by X-ray powder diffraction results. The dependence of Pr3+ ion concentration in GdPP:Sm,Pr crystals on the emission intensity of 4G5/2→6H7/2 transitions of Sm3+ ion and the energy transfer between Sm3+ and Pr3+ ions have been investigated and discussed.
