Abstract:The absorption and fluorescence spectra of ethylene glycol and glycerol solution induced by UV light were studied respectively in the present paper. The most intense absorption wavelength for both of them was located at 198 nm. Moreover,fluorescence was detected when induced by suitable UV light,and the corresponding fluorescence spectra were listed. But there is no obvious relationship found between the fluorescence intensity and the excited wavelength,and a further research should be done. From the first derivative fluorescence spectra of ethylene glycol,it was concluded that under the UV light of 210 nm,the variation speed for relative intensity proved to be the fastest. In contrast,when excited by 225 nm,the speed proved to be the slowest. In addition,based on the quantum calculation and the transition from HOMO to LUMO of electronics in one-dimensional quantum well,the authors attempted to give out the value of absorption wavelength. In consideration of the bond-length variety brought out by the chain processing,the error between the experimental and calculation values should be apprehensible,and the latter can serve as some reference value in theory.
