The effect of La3+ ion doping on the crystallographic, optical and electronic properties of CuO nanorods

Abstract

We have synthesized one-dimensional (1D) Cu100− xLaxO nanorods (NRs) by Co-precipitation method. The crystallographic phase, and morphology are analyzed using XRD, micro-Raman, XPS and TEM. The length and diameter of the Cu100− xLaxO NRs (x = 0.0, 0.5, 1.0) are ∼250–300 and 22–25 nm. The effect of La3+ ion doping on the optical properties have been analyzed using diffused reflectance spectroscopy. The strategy of utilizing La3+ ion as dopant for CuO worked out positively, as evidenced by impedance spectroscopy study. Our work provides valuable insights into the design and utilization of 1D Cu100− xLaxO NRs for practical application in optoelectronics. © 2018 Elsevier B.V.
