碩士 === 國立虎尾科技大學 === 光電與材料科技研究所 === 98 === This study enhances the ultraviolet sensitivity of Love wave photodetector using nickel－doped ZnO nanorods. The Love wave photodetector was fabricated using a ZnO guiding layer with nanorod arrays deposited on a 90°-rotated ST-cut (42°45) quartz substrate. Dense crystalline ZnO thin films were deposited by radio frequency magnetron sputtering. The nickel－doped ZnO nanorod arrays were synthesized on a ZnO thin film via the hydrothermal method. The crystalline structure, surface morphology and luminescent characteristics of films and nanorod arrays were examined by X-ray diffraction, scanning electron microscopy, and photoluminescence spectrometer. This study investigated the effects of the interaction of the Love wave with the ultraviolet light in the ZnO guiding layer on shift of insertion loss, phase shift of transmitted signal. The ultraviolet sensitivity of the Love wave photodetector was enhanced by adding nickel－doped nanorod arrays to the guiding layer.
