摘要：

We have measured transient absorption spectra of TiO2 under several pH conditions. We successfully extracted the spectral contribution of two different trapped holes from the transient absorption spectra. Based on the results, we discuss the origin of absorption spectra of holes in TiO2. (c) 2007 Elsevier B.V. All rights reserved.
