Investigation of UV photodetector properties of zirconium (Zr)-doped zinc oxide (ZnO)
Source abstract
Abstract
We report the effect of Zr-doping on the structural, morphological, optical, and UV detection properties of ZnO samples. Pure and zirconium (Zr) (1 wt%, 3 wt%, and 5 wt%)-doped ZnO samples are prepared by the conventional hydrothermal method. The X-ray diffraction (XRD) analysis revealed hexagonal wurtzite structure of ZnO. Hi-resolution scanning electron microscope (HR-SEM) images showed the formation of hexagonal nanoprism morphology in all the samples. In XPS data analysis, it was found that the 3 wt% sample had larger area for oxygen vacancies as compared to other samples. Over the UV illumination these oxygen vacancies increases the number of electrons thereby increase the photocurrent of the sample. The improvement in UV detection properties of 3 wt% Zr-doped ZnO samples makes them useful for optoelectronic applications.Graphical abstract
