Abstract

Praseodymium-doped borovanadate glasses were prepared by conventional quenching melt technique. The prepared composition was [90 Na₂B₄O₇-(10 - x)V₂O₅-x Pr₆O₁₁], x = 0, 0.5, 1, 2, 4, 6, 8 and 10 mol%. Optical absorption spectra have been investigated in the spectral range from 195 to 2500 nm. Experimental oscillator strengths of the observed bands have been estimated and used for calculating the Judd-Ofelt (JO) intensity parameters. Radiative transition probabilities as well as branching ratios were calculated. The radiative lifetime of the ¹D₂ and ³P₀ levels was varied from ca. 344 to 808 μs and ca. 30 to 63 μs respectively. The optimum Pr concentration at which the branching ratios have the maximum values was obtained at 1 mol%.
