摘要：

In this paper, we presented a comparison of Photoluminescence (PL) studies of Gd2O3 phosphor prepared by two synthesis methods, high temperature (1400 degrees C) solid state reaction and low temperature combustion synthesis. Both of these methods synthesized Gd2O3 phosphor successfully. Structural properties of Gd2O3 phosphor were investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR). Scanning electron microscope (SEM), Energy dispersive X-ray analysis (EDX), and Transmission electron microscopy (TEM). The results obtained for both methods of preparation were compared. The photoluminescence (PL) properties of pure Gd2O3 were carried out over the range of 300 nm -650 nm. A PL emission band at UV region in between 318 and 370 nm along with blue, green and red emission was observed at 275 nm excitation.
