【摘要】 本文在较前人宽的波段内系统地研究了REP₅O₁₄(RE=Ce³⁺,Pr³⁺,Nd³⁺,Sm³⁺,Eu³⁺,Gd³⁺,Tb³⁺,Dy³⁺,Ho³⁺,Er³⁺,Tm³⁺,Yb³⁺)单晶的吸收光谱、激发光谱与荧光光谱。合理地确定了谱项。关于SmP₅O₁₄,GdP₅O₁₄,DyP₅O₁₄,TmP₅O₁₄与YbP₅O₁₄等晶体光谱的研究,至今尚未见报导。这些晶体系统的光谱数据,对于了解它们的性质及其应用方面,都是很有用的。更多还原

【Abstract】 In this paper, the series of absorption,excitation and emission spectra of REP5O14 (RE = Ce3+, Pr3 + , Nd3+ , Sm3 + , Eu3 + , Gd3 + , Tb3 + , Dy3+, Ho3+, Er3 + , Tm3 + , Yb3 + ) single crystals were investigated in a wavelength region much larger than those reported so far. The spectral terms were assigned reasonably, and some mistakes in previous papers were corrected. Particularly, the spectra for GdP5O14, DyP5O14, TmP6O14, YbP5O14 and SmP5O14 were measured in detail. They have not been reported previously. These spectral data will be very useful to understand the properties of REP5O14 crystals and to utilize them.更多还原
