<p>We report the synthesis and characterization of Gd³⁺ activated LaCePO₄. The phosphors were synthesized by a modified solid-state reaction method with variable concentrations (0.5–2.5 mol.%) of doping ions of Gd³⁺. Analyses of the sample's structure have shown that it had a monoclinic structure with a single phase. Micro-crystal formation was seen using scanning electron microscopy (SEM) of particles ranging in size from ~100 nm to over 2 μm. FTIR confirmed the formation of LaCePO₄:Gd³⁺ phosphor. Phosphor samples with varying doping ion concentrations were also shown via photoluminescence analysis. LaCePO₄:Gd³⁺ phosphor emits intense near-UV-blue light by 275-nm excitation. The corresponding spectroscopic parameters were calculated using the CIE technique, and the coordinates (<i>x</i> = 0.17 and y = 0.20) were in the visible region. Based on the findings, phosphor produced in such a way might be used in laser applications. Thermoluminescence (TL) glow curve analysis for various UV exposure times (5–20 min) showed a good broad TL glow curve centered at 183°C. The broad TL glow curve was deconvoluted by the CGCD program, and the corresponding trap parameters were calculated.</p>
