Descrição: Nanostructured one-dimensional (1-D) ZnO arrays fabricated via pulsed electrodeposition and coated with Ag nanoparticles are researched with the aim of their using in the ultraviolet (UV) photosensors. The results of the crystal structure investigations showed that the pulsed electrodeposited zinc oxide arrays are polycrystalline in nature and matching with hexagonal wurtzite modification of ZnO. To enhance its UV photosensitivity, the silver nanoparticles (AgNPs) with different shape and an average size of 60 nm, as well as 300-500 nm long Ag nanorods with ~30 nm diameter, are precipitated mainly on the (002), (101) and (100) ZnO planes. Study of electrical properties and electronic parameters of the 1-D ZnO and Ag/ZnO nanocomposites using a current-voltage and capacity-voltage characteristics identified the important role of the high double Schottky barriers at the ZnO intergrain boundaries for the creation of great UV photosensitivity. It is proved that through monitoring the amount of AgNPs on the ZnO surface the electrical properties and electronic parameters of the Ag/ZnO nanocomposites, and consequently, the output parameters of the UV photosensors can be controlled.
