摘要
Highly transparent and conducting molybdenum oxide (2, 3, 4 wt%) doped indium oxide thin films are prepared using pulsed laser ablation. XRD and AFM analysis show that at higher MoO3 doping concentration (>3 wt%) inhibits grain growth due to the presence of Mo atoms at grain boundaries. The average size of the crystallites increases with MoO3 doping up to 3% and thereafter decreases. The doped films exhibited high values of optical transmittance and low values of electrical resistivity compared to undoped films. Beyond 3 wt% MoO3 doping, the optical and electrical properties slightly decline. The observed band gap widening in the films can be attributed to Moss-Burstein effect. All the films show intense PL emission in the UV-visible region. (C) 2012 Elsevier B.V. All rights reserved.
