| Abstract: | Carbon or chromium doped titania were synthesized by ball-milling.Carbon or chromium doping were used to control the degree of oxygen defects.The crystal phases and optical performance of samples were characterized by X-ray diffraction,UV-vis spectrophotometer and fluorescence spectrometer.The results showed the degree of oxygen vacancies for samples was changed by doping.In addition,the origin of absorption in the visible spectral range for carbon or chromium doped sample would also be discussed. |
