CdS-Sensitized ZnO Nanorod Photoelectrodes: Photoelectrochemistry and Photoinduced Absorption Spectroscopy
Figure 7
Photoinduced absorption (PIA) spectra of quantum CdS-modified ZnO-np (triangle) and ZnO-nr (square) electrodes in air. The spectra were recorded using blue light (460 nm) excitation (42 mW cm−2) with a modulation frequency of 9 Hz.
