Band gap engineering of nanostructure Cu doped CdO films

Luminescence and physical properties of copper doped CdO derived nanostructures

“…Insertion of copper ions reduces the grains as depicted in microphotographs (Fig. 5), similar trends were found by Gupta et al [33]. Nanoparticles of Cu doped CdO were obtained by solid state synthesis [34].…”

Bandgap variation in size controlled nanostructured Li–Ni co-doped CdO thin films

“…Multilayer matrices of alumina capped zinc oxide nanoparticles with mean radii in the range of 1.8-3.6 nm were grown using pulsed laser deposition method to obtain size-dependent bandgap up to about 4.5 eV [11]. Our recent studies have evidenced that the bandgap of the CdO could be tuned by copper (Cu) doping [12]. It was observed that the bandgap of the CdO film is decreased by Cu doping and among the Cu doped CdO films, the bandgap was observed to increase with increase in copper doping level.…”

“…Motivated by our previous results on Cu doped CdO [12], in this work we study the effect of co-doping (Li-Ni) on the structural and optical properties of CdO films. We have compared the properties of Ni doped and Li-Ni co-doped CdO films.…”

Effect of Annealing Conditions in Hydrogen Atmosphere on Structural, Optical and Magnetic Properties of Nanocrystalline CdO Codoped with Cu and Co Ions for DMS Applications

“…Incorporation of CdO with Cu 2+ ions of smaller size than that of Cd 2+ (the ionic radius of Cd 2+ and Cu 2+ are 9.5 × 10 and 7.3 × 10 −2 nm, respectively [7]) was studied several times [8,9], where it was confirmed that the unit cell volume of host CdO decreased with Cu doping and the conduction properties of host CdO was improved with Cu doping [9,10] that could, in turn, assist or support the medium for magnetic mutual interactions, i.e. Cu 2+ ions are employed as a magnetic catalyst.…”
