Concentration Dependence Orange Light Generation Through Sm3+-Doped Soda Lime Alumino Borate Glasses for Orange Laser Medium Material

초록

The melt-quenching technique is used to fabricate calcium sodium aluminum borate glasses (Sm: ANCB) doped with varying concentrations of Sm3+ ions. Characteristics of ANCBSm glasses, including density, molar volume, refractive index, absorption, emission (via visible light, X-ray, and proton excitation), decay time, and CIE color coordinates, are analyzed. The density, molar volume, and refractive index of ANCBSm glass increased with Sm2O3 concentration. Sm3+ ions enabled photon absorption in both visible and NIR regions, with a strong reddish-orange emission at 600 nm due to the H-6(5/2) -> P-6(3/2) transition under various excitations. X-ray excitation is also compared with BGO scintillation crystals. The J-O theory predicted the radiative properties of Sm3+ ion emission levels. Decay curves of the H-6(5/2) levels showed a single exponential nature with a millisecond-order lifetime. CIE chromaticity of ANCBSm glasses is in the reddish-orange region. ANCBSm glasses have potential applications in orange laser medium material.
