Judd–Ofelt (JO) theory explains the optical properties of trivalent lanthanides using only three intensity parameters. The JO parametrization is a complicated procedure of absorption spectra analysis, especially cumbersome for powders and non-transparent materials. For the Pr³⁺ activated materials, the procedure is additionally complicated due to strong interaction of low-lying Pr³⁺ 4f5d energy levels with the 4f levels. Here, the straightforward JO parametrization method that uses the emission spectrum and the excited state lifetime of the Pr^{3+ 3}P₀ level which does not require any fitting procedure are shown. In addition, the theory and software for calculations of JO parameters from Pr³⁺ emission are explained. The method requirements are low-temperature photoluminescence measurements of Pr³⁺ introduced in low phonon energy hosts with a relatively high lying 4f5d energy level. The method is demonstrated on emissions of YF₃:Pr³⁺ and LaF₃:Pr³⁺ powders.

Pr3+ 掺杂材料发射光谱的 Judd–Ofelt 参数化：Pr3+ 掺杂 YF3 和 LaF3 的理论、应用软件和演示

Judd-Ofelt (JO) 理论仅使用三个强度参数解释了三价镧系元素的光学特性。JO 参数化是一个复杂的吸收光谱分析过程，对于粉末和非透明材料尤其繁琐。对于 Pr ³⁺活化材料，由于低位 Pr ³⁺ 4f5d 能级与 4f 能级的强相互作用，该过程更加复杂。在这里，显示了使用发射光谱和 Pr ^{3+ 3} P ₀能级的激发态寿命的直接 JO 参数化方法，不需要任何拟合程序。此外，从Pr ³⁺计算JO参数的理论和软件发射进行了解释。该方法的要求是在具有相对较高的 4f5d 能级的低声子能量宿主中引入的 Pr ³⁺的低温光致发光测量。该方法针对YF ₃ :Pr ³⁺和LaF ₃ :Pr ³⁺粉末的排放进行了演示。
