摘要： 由纤维素铜氨溶液与钒磷酸钇:铂,铝酸钡镁:铕,硫比锌镉:铜和硅酸锌:锰荧光粉混合分别制备了4种再生纤维素荧光膜,研究了这些膜的荧光光谱、相对荧光强度、结晶度及力学性能变化.实验结果表明当添加5%荧光粉时,含钒磷酸钇:铕,铝酸钡镁:铕和硫化锌镉:铜的膜仍保持荧光粉的结晶峰,在紫外光照射下分别发出红、蓝、黄荧光,其相对荧光强度依次为81%、79%及74%.当膜含5%硅酸锌:锰时,在紫外光照射下发射微弱的绿光,相对荧光强度显著下降,并且荧光粉的结晶被破坏,然而该再生纤维素膜的结晶度和力学强度却增高.

Abstract: Four kinds of fluorescent films of regenerated cellulose were prepared by mixingcellulose cuoxam solution and fluorescent powders including Y(PV)O4: Eu, BaMg2Al16O27:Eu,(Zn,Cd)S: Cu and Zn2SiO4 :Mn,respectively. The fluorescence spectra, fluores-cence intensity,degree of crystallinity and mechanical property of these films have been stud-ied.The resuIts showed that the peak of crystallinity of fluorescent powder remained unchanged when the film had 5wt% of fluorescent powder of Y(PV)O4: Eu,BaMg2Al16O27:Eu and(Cd,Zn)S:Cu under inradiation of ultraviolet light these films emitted strong red,blue,and yellow light with the fluorescence intensities being 81%,79%and 74%,respec-tively. However, film containing 5%Zn2SiO4:Mn only emitted slightly green light and thestructure of crystal of the fluorescent powder in the film was brocken and the degree of crys-tallinity and mechanical preperty of this film increased significantly.
