Effect of high energy electron beam irradiation on the optical properties of nanocrystalline TiO2
Abstract
The effect of high energy electron beam irradiation on the optical properties of TiO2 nanoparticles was studied in order to improve the optical absorption performance and photo-activity. Electron beam irradiation may have resulted in size reduction, which in turn caused an increase of the optical band gap and photoluminescence intensity. Irradiation at a suitable dose rate was found to enhance the optical absorption performance and photo-activity of the tested TiO2 nanoparticles.
