Abstract
Ag2S quantum dots (QDs) were deposited on ordered TiO2 nanotube arrays (TNTAs) using a sequential chemical bath deposition (S-CBD) approach. AgNO3 and thiourea were used as the precursor materials of Ag+ and S2− ions, respectively. The decoration of Ag2S QDs significantly shifted the absorption spectrum of the TNTAs to visible light region. As a result, Ag2S QDs-sensitized TNTAs exhibited much higher photocurrent density than pure TNTAs under visible light irradiation.
