  • Samarium doped B2O3-Na2O-Li2O (BNaLi) [u1] glasses with concentration of 0.5 mol% were prepared by the conventional melting procedure. Optical absorption, excitation, luminescence spectra and lifetime have been measured at room temperature. Judd – Ofelt (JO) theory is used to study the spectral properties and to calculate the radiative transition probabilities. The predicted[u2] branching ratios (βR), radiative lifetime (ιR) and stimulated emission cross-sections [u3] (σ(λp)) of the 4G5/2 excited level are reported.

  • Double potassium gadolinium fluoride crystal doped with 5.0 mol % of Dy3+ ions (K2GdF5:Dy3+) was synthesized under hydrothermal condition. The absorption, luminescence spectra and lifetime of K2GdF5:Dy3+ sample were measured at room temperature. Judd – Ofelt (JO) theory is used to study the spectral properties and to calculate the radiative transition probabilities. The prediced branching ratios (βR), radiative lifetime (ιR), integrated emission cross – section (Σif) and stimulated emission cross – sections (σ(λp)) of the 4F9/2 excited level are reported.[u1]
