Figure 5

Photoluminescence spectra of glass substrate as well as the AZO nanorod array thin film. Photoluminescence spectra of glass substrate as well as the AZO nanorod array thin film with hydrogen treatment and those sensitized by CdS nanoparticles for different cycle numbers. The excitation wavelengths were 325 (a) and 460 (b) nm.
