dc.description.abstract본 연구에서는 고상법 및 flux를 이용하여 Y3Al5O12 : Er 3+ (YAG : Er 3+ ) 분말을 저온에서 성공적으로 합성하였다. 분말의 합성 여부와 분말 하소 시 온도에 따른 결정성을 분석하기 위하여 X-ray diffraction(XRD)를 측정하였다. 순수한YAG는 일반적인 고상법으로 합성할 경우, 1400 o C에서 12시간 동안 하소하여 순수한 YAG 상을 얻을 수 있었고, 반면에BaF2를 첨가한 결과는 상대적으로 낮은 온도(1000 o C)에서 합성되었다. 즉, 합성온도를 약 400 o C 가량 낮출 수 있는 것으로나타났다. 또한, BaF2의 최적의 농도를 찾아 첨가 후, 열처리 온도에 따라 BaF2로 인한 입자의 형태 및 크기를 조사하였으며 그에 따른 발광강도에 대하여 논의하였다. In this study, using solid-state and flux, Y3Al5O12 : Er3+ (YAG : Er3+) 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 1400oC and pure YAG phase could be obtained. But when BaF2 was added to YAG, YAG was synthesized at lower temperature (1000oC). It was thus found that the synthesis temperature could be lowered by about 400oC. Also, when BaF2 with an optimal concentration was added to YAG : Er3+, the particle shape and size according to synthesis temperatures were surveyed, and corresponding luminous intensity was discussed.en_US
