摘要：

We report the observations of electroluminescence of photodegraded poly(p-phenylenevinylene) derivatives film which was irradiated with laser light at a wavelength in the region of ultraviolet. EL spectral change for different polymers shows different behaviour. Electroluminescence and photoluminescence intensities of PPV decreases rapidly and the intensities in the blue region become relatively severe without peak shift. MEH-PPV shows the blue shift of the peak in EL spectra with negligible intensity decrement. Spectroscopic results of the PPV film degraded by UV light support the photodegradation occurred by chain-scission process.
