Fluorescence Studies of Nd+3 Ions in Phosphate Glass

Abstract

Tripositive neodymium ion doped phosphate glass has been prepared by melt-quenching technique. The final composition (by weight) was approximately Na(PO3)670%-BaO15%-PbO 10%- Al2O3 5%-R Ln (Where R=0.5% and Ln= Nd +3 ). The experimental oscillator strengths were calculated from the areas under the absorption bands. Judd-Offelt parameters (Ωλ) evaluated using the observed spectral intensities have been used to compute various laser parameters viz., spontaneous emission probability (A), radiative life time () and stimulated emission cross-section (p). The bonding environment surrounding the rare earth (RE) ion has also been discussed.
