Research on Preparation and Luminescence Properties of Tm3+ -doped Glass Ceramics Containing NaLa(MoO4)2

Abstract

In the world of light-emitting diodes, Tm3+-doped glass ceramics are a crucial fluorescent material. In this study, melt-crystallization was used to create glass ceramics that were Tm3+-doped and included crystalline NaLa(MoO4)2. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmittance, and photoluminescence spectroscopy were used to examine the structure, morphology, and luminescence characteristics of glass ceramics (PL). According to the findings, keeping the precursor glass at 660 °C for two hours produced microcrystals with an average size of 280 nm. Also covered is how the concentration of Tm2O3 doping affects the luminous characteristics of glass ceramics. The strongest blue light is produced at 454 nm (1D2→3F4) when Tm2O3 concentration is 0.8 mol%. The findings demonstrate that Tm3+-doped glass ceramics containing NaLa(MoO4)2 crystalline phase have promise for use in the area of color displays.
