Abstract
A series of Eu3+-doped (Y(1−x)Lax)PO4 phosphors were synthesized using a slow evaporation method increasing molar ratios of La3+ ions in (Y(1−x)Lax)PO4:0.01Eu3+. The crystal structure and photoluminescence (PL) with decay curves of the samples were characterized using X-ray diffraction (XRD) and fluorescence spectroscopy, respectively The PL intensity is higher for the monoclinic than tetragonal structure of the (Y(1−x)Lax)PO4:Eu3+ phosphor. The CIE color coordinates shows that the color purity increases, when the La3+ ions are completely replaced by Y3+ ions.
