Judd-Ofelt分析
Judd-Ofelt analysisA theoretical framework used to analyze the intensity of electric dipole transitions in rare-earth ions within a host material. It relates the measured absorption spectra to the local atomic environment and the radiative properties of the ions. / 一种用于分析稀土离子在基质材料中电偶极跃迁强度的理论框架。它将测量的吸收光谱与离子的局部原子环境及辐射特性联系起来。
