Ag islands and nanorods (NRs) array were fabricated through glancing angle deposition (GLAD) method at an angle of 85 °C by using thermal evaporation technique. Subsequently, ZnO NRs were grown along the side of Ag NRs arrays through hydrothermal reaction. The crystal structure of ZnO/Ag hybrid structure was studied by Glancing Incident X-Ray Diffraction (GIXRD). The surface morphologies of Ag NRs arrays and ZnO NRs were studied through AFM and SEM techniques. The presence of different vibrational energy modes of ZnO structure was studied through confocal Raman spectrometer. The surface plasmon enhanced fluorescence of ZnO NRs was probed through fluorescence spectrophotometer. The presence of strong UV emission and the absence of intense visible emission of ZnO NRs are due to the existence of fewer crystal defects which could make the hybrid structure precious for UV LEDs.
