摘要

本文通过对不同波长紫外光激发乙醇水溶液的荧光光谱分析

系统地讨论了水对乙醇溶液荧光光谱的影响.结果表明高浓度乙醇溶液在紫外光的激发下会出现350nm和550nm两个发射峰.随着激发波长增加

在350nm的荧光峰值出现红移

荧光强度先增大后减小

在550nm的荧光峰强度出现猝灭

呈现出先减小后增大的趋势.当乙醇的体积分数从50%增加到100%时

在550nm处的荧光峰强度先减小后增加.乙醇体积分数从20%增加到75%时

在350nm处的荧光峰强度先增加后减小.

Abstract

The fluorescence of ethanol-water mixture excited by ultraviolet light and the excitation spectra corresponding to the fluorescence peaks at 350 nm and 550 nm are investigated respectively. With the increase of the UV excitation wavelength

the fluorescence peak of ethanol-water solution moves toward to the longer wavelength in 350 nm

and the fluorescence intensity increases at first and then decreases afterwards. The fluorescence intensity of 550 nm peak has different degrees of quenching

showing the trend of decreasing at first and then increasing. When the volume percent of ethanol-water solution from 50% increases to 100%

the fluorescence peak intensity decreases at first and then increases at 550 nm

but the fluorescence intensities without any significant changes at 350 nm under 310 nm and 330 nm excitation. With the increase of the volume percent of ethanol-water solution from 20% to 75%

the fluorescence intensity increases at first and then decreases at 350 nm with 280 nm excitation wavelength.
