چکیده انگلیسی
Lu2SiO5:Cex,Nay (x = 0.002–0.016 and y = 0.01–0.08) phosphor was prepared by sol–gel method. The effect of Na+ ions on the crystallization behavior and luminescence properties of LSO:Ce phosphor was investigated by X-ray diffraction (XRD) and spectral measurement. The results indicated that the crystallization temperature of LSO was reduced from 1200 °C to 1000 °C by Na+ doping. The luminescence intensity of LSO:Ce phosphor under UV and X-ray excitation was much improved by Na-doping and the dopant concentration of the sample with maxima luminescent intensity was at x = 0.006 and y = 0.02. And the relationship between Na-doing concentration and the luminescent properties is discussed.
