Abstract：The fluorescence spectra of low concentration diethyl ether-water solution excited by different UV light, and the variation rule of the fluorescence characteristic along with the incidence light wavelength and the solution concentration were studied. Also the emission mechanism together with the spectral characteristic were analyzed. The result shows that the ether solution exhibits an obvious fluorescence peak nearby 306 nm, for which the best excitation wavelength is 245 nm, moreover, there is an inferior peak at 292 nm. The shape of the fluorescence spectrum is invariable ultimately along with the change in excitation light wavelength, and the peak value assumes the Gaussian distribution with the stimulation light wavelength. Meanwhile the emission intensity of the inferior peak and that of the prominent peak are in competition with each other. With increasing the concentration, the fluorescence intensity at 306 nm strengthens linearly, and after increasing the concentration to 7%, concentration-quenching occurs, so the intensity linearly weakens. The findings can provide the reference for detecting concentration and purity of the virulent and anesthetic matter-diethyl ether and so on.
