摘要
We have observed the enhancement of photoluminescence in poly(p-phenylenevinylene) thin films under laser beam irradiation by a spectrally resolved laser scanning microscope. The photoluminescence is found to increase at the very start of irradiation. However, extended exposure would also lead to decrement in photoluminescence and burned-out spots as reported previously. This enhancement effect may correspond to the many stages during the photo-induced reaction.
