Correlation of radiative properties of rare earth ions (Pr3+ and Nd3+) in chlorophosphate glasses�??0.1 and 0.5 mol% concentrations

[摘要] Optical properties of chlorophosphate glasses of the type 50P₂O₅â€�??30Na₂HPO₄â€�??20RCl (R = potassium and lead) activated by 0.1 and 0.5 mol% of Pr³⁺ and Nd³⁺ have been investigated. Optical band gaps (𝐸_opt) have been reported for 0.1 and 0.5 mol% concentrations of Pr³⁺ and Nd³⁺ doped potassium and lead chlorophosphate glasses. Energy levels and optical transitions of Pr³⁺ and Nd³⁺ are assigned. Spectroscopic parameters (𝐸¹, 𝐸², 𝐸³, ðœ�?_4f and ð›�?), spectral intensities (ð‘�??_expt), Juddâ€�?�Ofelt intensity parameters (ð›�?₂, ð›�?₄ and ð›�?₆) and radiative lifetimes (𝜏_R) are correlated for 0.1 and 0.5 mol% concentrations of these two ions in potassium and lead chlorophosphate glasses
