Abstract
A cellulose-assisted, liquid-phase precursor (LPP) was used to synthesize a YAG phosphor radiating near 530â¯nm with a particle size of 400â¯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 1400â¯Â°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: 3.1â¯M). â¼400â¯nm particles were obtained at 1200â¯Â°C and â¼1â¯Î¼mâ¯at 1300â¯Â°C. At 1200â¯Â°C, the PL intensity was the highest in the Y3.1Al5O12 sample. At 1300 and 1400â¯Â°C, the strongest intensity was evident in the Y2.9Al5O12 sample. The XRD patterns for all temperatures showed a YAG phase in JCPDS.
