摘　　要：以Tb3+离子为亚相,成功制备了对十六烷氧基苯甲酸铽的LB膜。研究了对十六烷氧基苯甲酸在纯水和稀土亚相上的单分子行为。红外光谱,紫外光谱表明了亚相稀土离子与羧酸基头发生了配位作用。LB膜在紫外光照射下发出较强的绿色荧光,荧光光谱显示LB膜具有良好的发光性能。The LB films of 4hexadecyloxybenzoicterbium were successfully prepared by using the subphase containing Tb3+. The monolayer behavior of 4hexadecyloxybenzoic acid on the subphase containing rare earth ions was studied. The πA isotherm showed that the coordination tooks place between the monolayer and rare earth ions. The LB films were characterized by IR, UV and luminescence spectra. The luminescence spectra show that the LB films have fine luminescence properties, and LB films give off strong luminescence under UV light irradiation.
