| 摘 要： | 分别从理论和实验上对紫外光激励不同浓度的乙醇溶液所产生的荧光光谱及其特性进行了分析研究。结果表明,在波长为254nm的紫外光激励下,乙醇溶液可以产生较强的荧光,其峰值为395nm,经研究认为该荧光是由乙醇分子中C-OH基团的孤对电子产生的。研究乙醇溶液的荧光光谱及其特性可为其作为有机溶剂对其它物质的荧光光谱进行研究提供参考。

| Abstract: | The fluorescence spectra of alcohol solution induced by ultraviolet light and its characteristic are studied experimentally and theoretically in this paper. The results show that alcohol solution can emit strong fluorescence at 395nm when excited by ultraviolet light with the wavelength of 254nm.It is considered that this fluorescence comes from the transition from n→σ* of the lone-pair electrons in the hetero atom group (C-OH) of the ethanol molecule. Investigation on the fluorescence spectra and its characteristics will contribute to study of other organic macromolecule fluorescence spectra when alcohol serves as solute. |
