摘要: 采用溶剂热法，乙醇和乙二醇为混合溶剂，160℃条件下，反应12小时，成功制备了LaF3:Ce3+/Tb3+晶体。并用聚丙烯酸(PAA)对材料进行了功能化，红外吸收光谱显示材料表面成功修饰上羧基(-COOH)。以275 nm为激发波长，LaF3:Ce3+/Tb3+及COOH-LaF3:Ce3+/Tb3+晶体的发射波长均为526 nm，而功能化的LaF3:Ce3+/Tb3+荧光强度较低。
Abstract: The LaF3:Ce3+/Tb3+ crystals were prepared using solvothermal method, at 160˚C for 12 h in the mixed solvents of ethanol and glycol. The as-prepared LaF3:Ce3+/Tb3+ crystals were functionlized with Poly(acrylic acid). IR absorption spectra showed that the carboxyl group (-COOH) is on the surface of LaF3:Ce3+/Tb3+ crystals. Under 275 nm excitation, the emission peaks of LaF3:Ce3+/Tb3+ and COOH-LaF3:Ce3+/Tb3+ crystals locate at 526 nm. Moreover, the fluorescent intensity of the functional LaF3:Ce3+/Tb3+ is lower.
