Synthesis design of Y3Al5O12: Ce3+ phosphor for fabrication of ceramic converter in automotive application

A cellulose-assisted, liquid-phase precursor (LPP) was used to synthesize a YAG phosphor radiating near 530 nm with a particle size of 400 nm, which may be implemented in many applications. The mixture of the materials was homogeneous, and the cellulose-assisted LPP method involved a liquid-phase reaction at a lower temperature compared to a solid-state reaction (SSR). The reaction was performed at 1200, 1300 and 1400 degrees C, and the composition ratio of the samples was controlled based on yttrium (L1: 2.7, L2: 2.8, L3: 2.9, L4: 2.95, and L5: 3.1 M). similar to 400 nm particles were obtained at 1200 degrees C and-1 mu m at 1300 degrees C. At 1200 degrees C, the PL intensity was the highest in the Y3.1Al5O12 sample. At 1300 and 1400 degrees C, the strongest intensity was evident in the Y2.9Al(5)O(12) sample. The XRD patterns for all temperatures showed a YAG phase in JCPDS.
