Abstract: Eu3+-doped LaPO4 powders were produced from direct liquid-liquid reaction of lanthanum chloride (LaCl3) and ammonium phosphate ((NH4)2HPO4). The sample was characterised by XRD and FTIR, which reveal that there is a phase transformation after the heat-treatment at 700°C. The optical properties of Eu3+-doped LaPO4 powders were investigated. Meanwhile, the influence of the dosage concentration of Eu3+ on the luminescent properties was studied. When above 5 mol%, the luminescence intensity decreases.

 

Keywords: Eu3+; LaPO4; phosphors; X-ray diffraction; XRD; FTIR; luminescence intensity; lanthanum chloride; ammonium phosphate; optical properties.
