摘要：
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.
