摘要
本文制备了掺铕的紫外光固化聚醚型聚氨酯膜 ,研究了光固化时间和铕浓度对膜的荧光性能影响 ,用扫描电镜及热重分析仪测定其均匀性和热稳定性。发现开始时膜的荧光强度随固化时间增加而增强 ,其后随固化时间的延长而减弱 。
Ultra light cross linking films of ether type polyurethane doped with Eu 3+ were prepared.The effects of the cross linking time and Eu 3+ concentration on the fluorescence properties were investigated,the film fluorescence intensity increased at first and then decreased.The scanning electron microscope observations show that the film was homogeneous.The thermal properties were also investigated.
