    • Abstract

       

      Optical properties of chlorophosphate glasses of the type 50P2O5–30Na2HPO4–20RCl (R = potassium and lead) activated by 0.1 and 0.5 mol% of Pr3+ and Nd3+ have been investigated. Optical band gaps (𝐸opt) 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, 𝜉4f and 𝛼), spectral intensities (𝑓expt), Judd–Ofelt intensity parameters (𝛺2, 𝛺4 and 𝛺6) and radiative lifetimes (𝜏R) are correlated for 0.1 and 0.5 mol% concentrations of these two ions in potassium and lead chlorophosphate glasses
