Abstract
The fluorescence properties of Eu3+-doped LaVO4, (La-0.75,Y-0.25)VO4, (La0. 5Y0.5)VO4 (La-0.25,Y-0.75)VO4, and YVO4 powder phosphors are reported. The phase purity was checked by XRD and FT-IR spectra. The values of relative f luorescence intensity ratios (R) and color coordinates ((X) over bar,(Y) ov er bar) were found to increase significantly with an increase in the yttriu m concentration. Both thermal analysis and scanning electron microscopy (SE M) studies were carried our to characterize the samples. (C) 2000 Elsevier Science Ltd. All rights reserved.
