Abstract: This paper studied fluorescence spectra of polyethersulphone (PES) in N,N'-Dimethyl formamide. It is found that there is only normal monomer fluorescence peak in the range of concentration from 0.0004mg/mLto 1 mg/mLunder normal case. Whereas excimer can be formed when it was irradiated by 280nm light beam, and Ic/Im is dependent on the irradiating time.
