単一微粒子半導体の光誘起反応を目指して For the Photoinduced Reactions at a Single Semiconductor Particle
Laser spectroscopy has been applied to investigating photoinduced or photocatalytic reactions on semiconductor particles. Furthermore, the laser photophysics of semiconductor nanoparticles is most important in the field of new materials. Recent investigations of single particles appear that a slight sizedistribution prevents accurate analysis in the photophysics. Since the photoinduced reactions have been studied so far on an ensemble of particles, the reaction on a single particle may provide a new insight into the heterogeneous reactions. Based on this aspect, in the present review, we comment on the photoinduced processes at the semiconductor, the recent development in the field of semiconductor nanoparticles, and the specific points of the photoinduced dynamics in the reaction system of nanoparticles. We referred recent reports on the photophysics and electronic properties of a single semiconductor nanoparticle, and suggest the possibility of developing new research field of single particle photochemistry.
