N2 - The influence of laser irradiation on an electroluminescent polymer, poly(2,5-di-n-hexyloxy-1,4-phenylene vinylene) is studied. Photoluminescence, infrared spectroscopy, and photothermal deflection spectroscopy were used to identify changes in the optical properties of the polymer after laser irradiation. It is found that optical irradiation leads to the opening of the vinyl double bond and decrease in conjugation length. Photo-oxidation of the polymer is believed to be responsible for the optical degradation of the polymer.
