[Study of 1-butanol absorption and fluorescence spectra induced by UV-light]

The absorption and fluorescence spectra of 1-butanol solution induced by UV-light and its characteristics were studied experimentally and theoretically. The authors found that 1-butanol solution shows a good absorption in 190-250 nm, and fluorescence was detected when excited by 210-250 nm. Fluorescence spectra of the mixed solution with 1-butanol and n-hexane were measured, and the fluorescence intensity shows a linear relationship with the volume ratio of the former. For the mixed solution of 1-butanol and alcohol, the authors found that at different wavelength, as the matching of 1-butanol and alcohol solution changes, the law for the intensity of fluorescence also changes. Meanwhile, the mathematical formula for the fluorescence position of the mixed solution was listed, and the error between calculation and experiment has been proved to be small. This may provide some reference for the further research of fluorescence spectrum of alcohol resolutions.
