Doping Effects on Optical Properties of Low Temperature Grown ZnO Nanorod Arrays

Abstract

In this work, we explore the influence of Ag dopant concentration on the structural and optical properties of ZnO nanorods synthesized by hydrothermal technique. We present original results of a systematic investigation of crystal quality, morphology and photoluminescence properties by using X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM) and photoluminescence (PL). Strong effects of doping in Ag-doped ZnO nanorod arrays on optical properties are observed. The main advantage of the proposed synthesis is its simplicity and fast growth rates. The strength of the proposed nanotechnology is that any substrate can be used to grow doped ZnO nanorods and transferable nanorods.
