| 摘 要： | 合成了化学组成为Ｙ１－ｘＴｂｘＬ３和Ｌａ１－ｘＴｂｘＬ３（Ｌ＝Ｃ８Ｈ７Ｏ２）的两种荧光粉，将其掺杂到聚丙烯中，制得两种聚丙烯荧光薄膜，通过测试机械性能，微分扫描式量热法分析，紫外分光光谱和荧光光谱测定，研究膜的物理和荧光性能。结果表明：这两种掺铽聚丙烯膜在３６５或２５４ｎｍ紫外光激发下，都能发出黄绿色荧光。掺入Ｙ１－ｘＴｂｘＬ３的聚丙烯膜的荧光强度大于掺Ｌａ１－ｘＴｂｘＬ３的聚丙烯膜。

| Abstract: | Two new fluorescent powders which have the chemical composition of Y 1-x Tb x L 3 and La 1-x Tb x L 3(L=C 8H 7O 2) were synthesized and doped to polypropyrene, and then two polypropyrene fluorescent films were prepared. The physical and fluorescent properties of these films were investigated by testing their mechanical parameters, DSC curves, UV absorption spectra and fluorescence spectra. The results show that the two terbium doped polypropyrene films can give out yellowish green fluorescence under 365 or 254 nm ultraviolet light exciation. Luminescence intensity of Y 1-x Tb x L 3 doped polypropyrene film is stronger than that of La 1-x Tb x L 3 doped polypropyrene film. |
