p-type Phosphorus doped ZnO nanostructures: an electrical, optical, and magnetic properties study

Author affiliations

Abstract

Well-arranged/self-assembled ZnO platelets with durable and reproducible p-type conductivity were synthesized using PCl5 as a dopant source via a simple low cost aqueous based chemical approach. Scanning electron microscopy and selected area diffraction pattern reveal pristine and doped ZnO nanostructures which are single-crystalline and grown predominantly along the [0002] direction. Split UV emission peaks in the photoluminescence spectra are located at 3.324 and 3.2714 eV, which could be attributed to acceptor bound exciton and free electrons to the acceptor emission, respectively. The relative intensity of defect-related broad-band emission (with respect to UV emission) ranging from 480–750 nm is enhanced significantly (ID/IUV = 1–0.056) in doped nanostructures, rendering the creation of defects. A systematic evaluation of room temperature ferromagnetism is found in pristine and doped ZnO nanostructures. p-type Doping is confirmed by photoluminescence spectra and the IV characteristic of phosphorus doped ZnO nanoplatelets.
