Structural and Optical properties of Some Metals Doped CdO Synthesized by Sol-Gel Method

Nanoparticles with crystallite size in the range 8.23-27.88 nm of transition metals (TM= Cr, Cu, Co, Ni, Mn, and Fe) doped (CdO) films were deposited by the sol-gel spin coating method. The strain, the grain size, lattice parameters and dislocation density were estimated from the XRD patterns. The calculated band gap for CdO is 2.302 eV and is increased with doping.
