C60掺杂聚苯乙烯薄膜的荧光发射
Fluorescence Propertion of Polystyrene Film Doped with C 60

摘要: 采用铸模的方法制得Ｃ６０掺杂的聚苯乙烯薄膜。Ｘ－射线衍射实验表明Ｃ６０已均匀分布在聚苯乙烯薄膜中，在氢离子激光器的激发下，发现该薄膜在５８３ｎｍ处有荧光发射，与空白样品的实验结果进行比较，发现该荧光发射为一新的荧光峰。详细的分析表明其是由于Ｃ６０与聚合物基质间的相互作用，使得跃迁禁阻能极化为跃迁允许能级而造成的。Abstract: A film of polystyrene doped with C 60 was prepared by the method of solution casting. Under the excitation of laser at 476.5 nm, the fluorescence spectrum of the film was measured at the room temperature. A new emission at 583nm has been found and de
