摘要: In this paper we describe a quantitative approach to the photochemical degradation of soluble dialkoxy–PPV that was also used make polymer light–emitting diodes. We have defined quantum yield for (γ) and investigated dependence on various experimental parameters, e.g. wavelength power incident light, oxygen concentration. presence main mechanism is photo–oxidation.
