Synthesis and characterization of ZnO:Ni thin films grown by spray-deposition

Effect of Cu, Ni and Pb doping on the photo-electrochemical activity of ZnO thin films

“…From the variations and disappearing of the peaks, it can be assumed that the doping of Ni modies the lm growth. Similar results can be observed by Nunes et al 50 and El Manouni et al 51 Also the degradation of the grain size upon Ni doping has been reported previously by Kim et al 52İ skenderoglu et al 46 studied the impact of Ni-doping on the properties of ZnO thin lms prepared by the spray pyrolysis technique. They found that the grain size decreased upon doping up to Ni-concentration of 6%.…”

“…46,49 The decrease in the band gap has been attributed to the strong sp-d exchange interaction between the band electrons and the localized 'd' electrons of the Ni ions substituted in the Zn sites in 10 at% Ni doping level. 46,62,63 In our work the band gap was found to be constant in the case of Cu and Ni doping lms while increasing in the Pb doped lm. The constant band gap in the Cu and Ni doped lms could be attributed to the low concentration of dopants which make no shi in the band gap value.…”

Nickel-doped zinc oxide thin films made by spray pyrolysis: experimental characterization and theoretical analyses

“…The value of E g obtained for the ZN0 sample was in good agreement with those in the literature for ZnO [2,31], while those of Ni-doped samples were also consistent with recent investigations in similar films [4,28,34,35].…”

Influence of yttrium doping on the structural, morphological and optical properties of nanostructured ZnO thin films grown by spray pyrolysis

“…Furthermore, the potential and versatility of ZnO based material for a wide range of applications [11], such as solar cells [15] [16] gas sensor [14] [18], phosphors [19] or as light-emitting diodes (LEDs) [20] have also been demonstrated. For these purposes, the properties of ZnO can be controlled by incorporating aliovalent elements as dopants, such as Al, Li, Sn, Ga or Ni [21,22][23] [24] [25], in order to improve its structural, optical and electrical features.…”
