摘要：

The Sm2O3-doped B2O3-K2O-PbF2 host glasses were synthesized by melt-quenching process. to comprehend visible luminescence and lasing potentiality, optical absorption, excitation, emission and decay measurement of developed glasses were studied. The experimental oscillator strength were calculated from absorption spectra of BKPFSm0.5 (optimized) glass sample. The decline in decay time as the proportion of samarium ions in the host glass increase indicates energy transfer between samarium ions. To establish potentiality of these glasses as visible lasers, the radiative properties of fluorescent transition acquired from photoluminescence emission spectra were determined. The quantum efficiency acquired from experimental and theoretical lifetimes was found to be 74% for the BKPFSm0.5 glass. The high quantum efficiency (eta), large stimulated emission crosssection (sigma(s) = 6.49 x 10(-22) cm(2)) and high branching ratios (beta(R) = 59%) for (4)G(5/2) -> H-6(7/2) transition of the BKPFSm0.5 glass specify acceptability of this glass for improvement of lasing (orange) and the photonic devices emitting the in visible region.
