Physical, optical and luminescence properties of Sm3+ doped lithium aluminium phosphate glass system

Sm3+ doped lithium aluminium phosphate glasses have been investigated in different concentration of Sm3+ ions. The physical, optical and luminescence properties were studied to evaluate their potential to using as orange color emitting materials. The result of physical properties indicated that the density, the molar volume and the refractive index of glass samples were increased with an increase of Sm2O3 content. The absorption spectra of glass samples were recorded in the wavelength range of 250-2000 nm. The absorption bands centered at 401, 473, 947, 1080, 1232, 1379, 1482 and 1532 nm have been observed. From the photoluminescence spectra, the glasses are showed strong emission at 597 nm which corresponds to (4)G(5/2)-> H-6(7/2) transition under excitation wavelength at 401 nm. The optimal concentration of Sm2O3 in lithium aluminium phosphate glasses was 0.5 mol%. (C) 2018 Elsevier Ltd. All rights reserved.
