| Popis: | In this article, Sm2O3 doped Lithium Alumino-borate (LABS) glasses were prepared by melt-quench technique. Physical, structural, thermal and spectroscopic properties are investigated by various techniques. The emission spectra consist of three sharp peaks at 562.5, 599, 645.5 nm within the 4f electronic configuration of Sm3+ ions and two feeble emission peaks at 691, 711 nm of Sm2+ ion at 402 nm excitation. Among all prepared glass samples, glass doped with 0.5 mol% Sm2O3 (LABS-4) shows highest emission intensity with CIE chromaticity coordinates x = 0.55 and y = 0.44 in the orange zone of the chromaticity diagram. The CIE plot and the images of glass samples show; the glass doped with 0.5 mol% Sm2O3 emit intense orange light at 402 nm excitation and can be useful for intense orange LED application. |
