详细研究了标称成分为25 BaF(2)-25SrF(2)-(30-x)Al(PO 3)(3)-xAlF(3)-(20-z)ScF 3:zREF(3)(x = 25、20和15,RE = Yb和Eu,0 F-7(1))的一系列氟磷酸盐玻璃的结构,以及Eu 3+发射能级D-5(0)的寿命值。其结果是,它是可能的,以获得一个全球性的解释在相关的定量配体分布(氟与磷酸盐)在第一配位领域的稀土离子。EPR和发光光谱的校准的基础上,这样的固态NMR数据定义了一个新的光谱策略,用于表征有前途的激光玻璃中的稀土局部环境。
A detailed structural investigation of a series of fluoride phosphate glasses with nominal compositions 25BaF(2)-25SrF(2)-(30-x)Al(PO3)(3)-xAlF(3)- (20-z)ScF3:zREF(3) with x = 25, 20, and 15, RE = Yb and Eu, and 0 F-7(1), and the lifetime values of the Eu3+ emitting level D-5(0). As a result, it was possible to obtain a global interpretation in terms of the associated quantitative ligand distribution (fluoride versus phosphate) in the first coordination sphere of the rare earth ions. The calibration of EPR and luminescence spectra on the basis of such solid state NMR data defines a new spectroscopic strategy for characterizing the rare-earth local environments in promising laser glasses.
