摘要
通过原位聚合制备掺杂Sm(TTA)3Phen的低黏度PMMA溶液,单面载玻片提拉成膜。借助傅立叶红外光谱仪(FT-IR)、扫描电子显微镜(SEM)、紫外-可见分光光度计(UVPC)、荧光光谱仪(PL)对掺杂PMMA复合薄膜进行形貌、结构、光学性能表征。结果表明:Sm(TTA)3Phen配合物在PMMA基材中仍然保持原有八配位结构;当Sm(TTA)3Phen转光粉掺量从1%到10%时,复合薄膜的可见光透过率均大于90%;3%掺量时,发射红光645nm处转光强度骤增为1%掺量的4.2倍,而后增加掺量,转光强度趋于平缓。采用低粘度提拉法成膜可以制备膜厚可控、高可见光透过、强荧光的PMMA转光膜。
Low viscous solutions contained polymethylmethacrylate（PMMA）/Sm（TTA）3Phen were prepared by insitu polymerization.Monolighic films were fabricated through dip-coating method.The morphology,structure,optical properties of these films were mainly characterized via fourier infrared spectrometer（FT-IR）,scanning electron microscope（SEM）,UV-Vis spectrophotometer（UVPC）and fluorescence spectrophotometer（PL）.The results discloseed that Sm（TTA）3Phen still keep the original eight coordination structure even doped into PMMA.The visible light transmittance of the films was higher than 90% when the dopant content reached 10wt%.The 645nm fluorescence intensity was drastically increased when the dopant content reached 3wt%then kep stable when increasing content of Sm（TTA）3Phen.It＇s more than 4time to the 1wt% dopant content film.The results indicated that the films can control well its thickness,and kep both high transmittance and high fluorescence intensity though low viscous dip-coating method.
