摘要
通过溶液浇铸法将四元铕配合物掺杂到乙烯-醋酸乙烯酯（EVA）中交联固化得到EVA复合膜，优化了制备EVA膜时固化温度、固化时间和引发剂加入量等工艺条件。通过紫外可见光光谱、荧光光谱研究了EVA复合膜的光学性能。结果表明，配合物在EVA中均匀分散；其掺杂量为1％时，EVA复合膜具有良好的可见光透过率，对200-400nm的紫外光有强吸收，并且能够发射出较强的红色荧光。
In this study, europium quaternary complex was doped into ethylene vinyl acetate （EVA） by casting method, and then an EVA composite film was produced through curing. The curing temperature, time and loading of initiator in EVA film were optimized. SEM showed that the complex was uniformly dispersed in EVA. UV and fluorescence spectra were used to characterize EVA composite film. It showed that when the doping amount of europium complexes was 1%, EVA film could emit strong red fluorescence through high absorption of 200-400 nm UV light and the visible light transmittance of EVA film was still good.
