Preparation of Ag/TiO<sub>2</sub>/ITO UV Detector and Its Photoelectronic Properties

TiO<sub>2</sub>-based UV detectors with Ag antidot/TiO<sub>2</sub>/ITO sandwich structure were prepared by RF magnetron sputtering and colloidal crystal template technology. The microstructure and photoelectronic properties of the UV detectors were investigated by SEM, XRD, f...
