摘要: 本文研究了聚醚砜(PES)的二甲基甲酰胺溶液的荧光光谱。发现在通常情况下,浓度在0.0004mg/mL~1mg/mL的范围内,只有聚醚砜的单分子荧光峰。但用波长为280nm的紫外光照射样品溶液能形成激基缔合物,且Ιem与照射时间有关。

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.

Key words: Fluorescence, Excimer, Polyethersulphone and irradiating
