Popis:	Environmental pollution with Dioxines has become one of critical issues. But its spectral characteristic is unknown. In this study, we conducted to detect the trace Dioxines by using laser-induced fluorescence (LIF). We investigated spectral characteristic of dibenzo-p-dioxine (DD) and dibenzofran (DF) in solvent (n-hexane) in ultraviolet wavelength region. As a result, we obtained the fluorescence spectrum by using pump-laser at a wavelength of 225nm with a pulse energy of 100μJ/pulse. Fluorescence peak wavelength of DD and DF were measured to be 300nm and 340nm, respectively.
