Abstract
We have observed the enhancement of photoluminescence in poly(p-phenyl enevinylene) thin films under laser beam irradiation by a spectrally r esolved laser scanning microscope. The photoluminescence is found to i ncrease at the very start of irradiation. However, extended exposure w ould 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.
