	<span style=\"line-height:1.5;\">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LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup>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，LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup>及COOH-LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup>晶体的发射波长均为526 nm，而功能化的LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup>荧光强度较低。<br />
The LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup> crystals were prepared using solvothermal method, at 160？C for 12 h in the mixed solvents of ethanol and glycol. The as-prepared LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup> crystals were functionlized with Poly(acrylic acid). IR absorption spectra showed that the carboxyl group (-COOH) is on the surface of LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup> crystals. Under 275 nm excitation, the emission peaks of LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup> and COOH-LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup> crystals locate at 526 nm. Moreover, the fluorescent intensity of the functional LaF<sub>3</sub>:Ce<sup>3+</sup>/Tb<sup>3+</sup> is lower.</span><span style=\"line-height:1.5;\"></span>
