Synthesis of Mn_0.04Cu_0.05Zn_0.91O nanorod and its application in optoelectronic switching device

The optical absorption of ZnO nanorod had been reduced by introducing Mn as doping element. In this present study the optical absorption of ZnO nanorod has been improved by simultaneous doping of the element Mn and Cu. The hydrothermal reaction was adopted for the synthesis. The electrical conductivity and the optical band gap of the Mn_0.04Cu_0.05Zn_0.91O were measured as 1.16 × 10⁻³Scm⁻¹ and 3.07eV respectively, assigned the semiconductor behavior. The light induced rectification in time dependent current response characteristic of Al/ Mn_0.04Cu_0.05Zn_0.91O/ITO was investigated to check the performance of the composite in opto-electronic switching device.
