Abstract

A novel sol-gel (SG) method has been proposed to synthesize the YAG:Ce phosphor. Raw powders of Y₂O₃, Al(NO₃) ₃ · 9H₂O and Ce(NO₃)₃ · 6H₂O were mixed and dissolved in water. No organic additives have been added. The gel with an inorganic Al/Y oxide framework was formed by heating the solution with continuous stirring, and then the precursors were fired at 1550°C under the reductive atmosphere. X-ray diffractometer (XRD) and photoluminescence (PL) measurements indicated that the pure and high performance YAG phosphors were obtained. Scanning electron microscopy (SEM) observation showed that the phosphor particles are well dispersed and nearly spherical with a homogeneous particle size. Electron paramagnetic resonance (EPR) measurement revealed that the proposed method could prompt the Ce ³⁺ ions to occupy the normal Y sites, leading to increased photoluminescence.
