摘要
在室温下,将MCM-41和热处理后的发光客体Eu(aspirin)3phen进行组装,通过XRD、N2-吸脱附和PL等表征技术对组装体进行了研究,考察其光致发光性能。结果表明:Eu(aspirin)3phen进入MCM-41孔道后,充当了'二次模板剂',使MCM-41的骨架有序性增加。经热处理后Eu(aspirin)3phen与MCM-41组装后,组装体的发光强度与相应Eu(aspi-rin)3phen粉末相当。未焙烧的MCM-41表面和稀土有机配合物成键后,Eu(aspirin)3phen分子出现反演中心,5D0→7F2跃迁明显减弱,而焙烧后MCM-41表面对Eu3+的5D0→7F2电偶极跃迁强度没有影响。
Assembly system with MCM-41 as a host,and Eu(aspirin)3phen which had been heat treated as an active optical guest was synthesized at room temperature.The structure and photoluminescence properties of the samples were investigated by XRD,N2 adsorption-desorption and PL.The results suggest that the framework order of MCM-41 increases after Eu(aspirin)3phen being incorporated into the channels of MCM-41.The luminescence intensity of Eu(aspirin)3phen-MCM-41,where Eu(aspirin)3phen has been heat treated,is equal ...
