Spectral properties of different concentrations of Nd³⁺ ion in barium lead borophosphate glass

Abstract

Multi-component oxide glass systems of barium lead borophosphate with 0.01-0.05 mol% of Nd ³⁺ion were prepared using meltquenching technique. The absorption spectral profile of these glasses in the UV-VIS regions was used to determine the spectroscopic characteristic parameters such as Racah (E¹, E², E³), spin orbit (ξ_4f), configuration interaction (<img src='/image/spc_char/alpha.gif' border=0>, <img src='/image/spc_char/beta.gif' border=0> and <img src='/image/spc_char/gamma.gif' border=0>) and Judd-Ofelt (Ω_2,Ω_4,and Ω₆) intensity factors. The radiative lifetimes (<img src='/image/spc_char/tow.gif' border=0>_R) and branching ratios (b) for the fluorescent levels have been reported for all concentrations of Nd³⁺ ion in the above glass systems.
