Abstract

Abstract: The paper reports that the light-scattering property of ZnO nanorods (NR) can be improved significantly in the near-UV/blue light region by Mg-doping. The NR were prepared using the hydrothermal method then characterized by scanning electron microscopy (SEM), X-ray diffraction, UV–Vis spectrophotometry. The results indicated that the average diameter and length of the NR reduced while the transmittance, band gap and light-trapping ability increased after the Mg-doping. The MgZnO NR shows significantly strong light-scattering parameter (average haze = 79.06%) over the undoped ZnO (43.29%) from 300 to 430 nm. This method presents a facile way for adjusting the light-trapping ability for ZnO thin films and the ZnO-based shortwave devices. Graphical abstract: Highlights: Mg-doped ZnO nanorods (NR) were fabricated by hydrothermal technique. MgZnO shows strong light-scattering with large haze (79.06%) in 300–430 nm. MgZnO exhibits high transmittance (81.60%), reduced reflection (28.95%). The enhanced scattering is from the decreased diameter and length after Mg-doping.
