摘要
The fluorescence lifetime of photo-oxidative emission at 360 nm becomes shorter when stabilizer is added to polyethylene film. A broad emission band at 450 nm is attributed to the emission from a charge transfer complex. The preliminary results show that the quenching of photo-oxidative emission and the fluorescence intensity decay can be used to evaluate the extent of photo-stability of polyethylene films.
