Abstract
In this study, using solid-state and flux, powders were successfully synthesized at low temperatures. To analyze the crystallinity of powders according to the synthesis or non-synthesis of powders and powder calcination temperatures, X-ray diffraction (XRD) was measured. In the case of pure YAG, when YAG was analyzed using the general solid-phase method, it was calcined for 12 hours at and pure YAG phase could be obtained. But when was added to YAG, YAG was synthesized at lower temperature (). It was thus found that the synthesis temperature could be lowered by about . Also, when BaF2 with an optimal concentration was added to , the particle shape and size according to synthesis temperatures were surveyed, and corresponding luminous intensity was discussed.
