Using a double-doping strategy to improve physical properties of nanostructured CdO films
(IOP PUBLISHING LTD, 2018) Aydi, R.; Sahin, B.
In this present study nanostructured dually doped samples of Cd1-x-yMgxMyO(M: Sn, Pb, Bi) are synthesized by SILAR method. The effects of the mono and dual doping on the structural, morphological and optoelectronic characteristics of CdO nanoparticles are examined. The SEM images verify that deposited CdO films are nano-sized. Also the SEM computations demonstrated that the morphological surface structures of the films were influenced from the Mg mono doping and (Mg, Sn), (Mg, Pb) and (Mg, Bi) dual doping. The XRD designs specified that all the CdO samples have polycrystalline structure exhibiting cubic crystal form with dominant peaks of (111) and (220). The results display that Mg and (Mg, Sn), (Mg, Pb) and (Mg, Bi) ions were successfully doped into CdO film matrix. The UV spectroscopy results show that the optical energy band gap of the CdO films, ranging from 2.21 to 2.66 eV, altered with the dopant materials.
