A new kind of TiO2 (NTA-TiO2(AB)) with single-electron-trapped oxygen vacancies was prepared by the dehydration of nanotubed titanic acid under vacuum. Under visible-light excitation (?ex=420 nm to 650 nm) NTA-TiO2(AB) showed a relatively intense emission, which red shifts with the increase of excitation wavelength. Analyzing the photoluminescence spectra, a sub-band induced by single-electron-trapped oxygen vacancies within Eg(NTA-TiO2(AB)) was obtained. [ABSTRACT FROM AUTHOR] |
