ZnO nanorods (NRs) are attracting the attention of many researchers because of their unique and enhanced properties thereby offering numerous potential applications in photonic, optoelectronic, spintronic, and piezoelectric devices,. The as-obtained results highlight the effectiveness of deposition temperature on Mg-doped ZnO NRs as an active layer during the fabrication of UV-LED device. The electroluminescence (EL) spectra under forward bias show that the diode emits a unique UV-light centered at 382 nm. The optimized tapering pyramidal-shaped Mg-doped ZnO NRs have also been grown onto p-GaN and the (ZnO:Mg NWs)/(p-GaN) heterojunction has been used to fabricate an LED device. X-ray diffraction analysis confirms the formation of pure single phase hexagonal (Wurtzite) structure while photoluminescence study shows a strong UV emission at 378 nm. At deposition temperature of 150 ☌ unidirectional tapering pyramidal-shaped Mg-doped ZnO NRs with high density was obtained, which is favorable for light-emitting diode (LED) application. Field-emission scanning electron microscopy observations reveal that both surface morphology and topography depend significantly on growth temperature.
