摘　　要：层状稀土氢氧化物层状材料(LRHs)因其独特的层状结构和层间离子交换能力,近年来吸引了较多的关注。采用微波法制备了LYH:Tb层状材料,通过离子交换的方式制备了邻氯苯甲酸、对氯苯甲酸、2,4-二氯苯甲酸插层的杂化材料。利用有机配体的“天线效应”,制备了一系列荧光性能显著增强的有机-无机杂化荧光材料。经原位自由基反应将这种杂化材料与PMMA结合后采用旋涂法制备了LRH:Tb-PAM复合薄膜,该薄膜展现出良好的透光性和光致发光特性。Due to the unique layered structure and ion exchangeable ability,the Layered Rare earth Hydroxides(LRHs)have attracted more and more attention in recent years.In this paper,the precursor layered material LYH:Tb were synthesized by microwave method.The intermediate hybrid materials intercalated with nonsteroidal anti-inflammatory drugs o-chlorobenzoic acid,p-chlorobenzoic acid and 2,4-dichlorobenzoic acid were prepared by ion exchange method.The hybrid material exhibited characteristic photoluminescence of Tb.Due to the“antenna effect”of ligand,the fluorescence intensity enhanced significantly.The composite P-CB/LYH:Tb/PAM film prepared by spin-coating method exhibited great transmittance and photoluminescence properties.
