Photocarrier Generation Process of Phthalocyanine Particles Dispersed in a Polymer: Effects of Pigment Particle Size, Polymer Matrix and Addition of Fine γ-Alumina Particles

概要

論文の詳細を見る
In systems of phthalocyanine particles dispersed in polymer, the effects of pigment particle size, electric property of the polymer and addition of fine γ-alumina particles on photocarrier generation efficiency have been studied. With smaller pigment particle size and higher dielectric constant of the polymer, the photocurrent increased. Addition of γ-alumina particles also caused a considerable increase in the photocurrent. It seemed that photocarrier generation occurred at the surface of the pigment particles and adsorbed oxygen played an important role in the process.
