摘要：

Molybdate glasses doped with Er3+/Yb3+ ions were fabricated using the high-temperature melting method, and transparent glass ceramics were obtained after heat treatment. XRD and TEM analysis results confirmed the formation of tetragonal nanocrystalline NaBi(MoO4)2. The structural characterization of glass and glass ceramics were investigated by Infrared and Raman spectroscopy. The transmittance of glass-ceramics in the visible range is over 60%. Compared to the glass, the up-conversion (UC) luminescence intensity of glass ceramics is enormously increased. And the UC luminescence intensity is correlated with temperature. Especially, in the aspect of temperature detection, the glass heated at 640 degrees C possesses a high absolute sensitivity of up to1.04% K-1, which can be applied in the field of optical temperature measurement.
