“…It has a high absorption coefficient in the visible range of the optical spectrum and enhanced electrical properties. 5 ZnS thin lms can be fabricated by molecular beam epitaxy (MBE), 6 sputtering, 7 metal organic vapor chemical deposition (MOCVD), 8,9 different wet chemical synthesis methods [10][11][12][13][14] and spray pyrolysis. The last technique is one of the simplest and efficient methods for fabrication of large area lms and it offers an easy way to incorporate any dopant by adding it to the starting spray solution.…”

“…The Cu can interact with intrinsic defects of ZnO resulting in formation of different defect complex which effect optical transitions in ZnO. It was found that this allows changing of the emission color from green to white [10]. Cu-doped ZnO has shown an essential improvement on electrical, optical, magnetic and luminescence performance [11].…”

The ZnO films were prepared by reactive rf-magnetron sputtering on silicon and sapphire substrates. For Cu-doping of the ZnO films, the close space sublimation method (CSS) was used at atmospheric pressure in air. After CSS processing, the ZnO and ZnO-Cu films were annealed in a wet media. The reference ZnO-Cu films, obtained from ZnO-Cu target by electron-beam evaporation (EBE) were treated at the same conditions. The microstructure and optical properties of the samples were compared and studied by atomic force microscopy (AFM), X-ray diffraction (XRD), photoluminescence (PL) and cathodoluminescence (CL) spectra. XRD results indicated that all the ZnO films have a polycrystalline hexagonal structure. The surface and crystal quality of ZnO thin film was improved when doped with Cu. The shape of the spectrum depends on the method of doping. Spectrum of the reference ZnO-Cu films has green band only. Spectrum of ZnO-Cu films consists of three emission bands at doping by CSS. The first band is in a blue region with a maximum at 465 nm. The second and third bands are in the green and orange regions with maximum at 520 and 580-600 nm, respectively. The green band is the most intensive. As a consequence, the emission looks like white light. Origin of observed emission bands is discussed.

“…In the last few years, ZnO has emerged as one of the most promising materials due to its optical and electrical properties, high mechanical and chemical stability, together with its abundance in nature and nontoxicity. In order to improve the properties of ZnO films, several techniques such as sputtering [6][7][8][9][10], thermal evaporation [11], metal-organic chemical vapour deposition [12,13], spray pyrolysis [14] and pulsed laser deposition [15][16][17] have been applied for their production. Radio-frequency (RF) magnetron sputtering technique is one of preferred among these techniques since it is versatile and permits to produce the high-quality films for different applications.…”

“…The structural, physical and electrical properties of ZnO films were governed by deposition parameters [14], posttreatment [7,17,18] and doping material [6,15,12,[19][20][21][22] such as Al, Ga, Sc, Y, Mn, Cu, Ag, etc. In addition, it is known that the metals of group I (Ag and Cu) are fast-diffusing impurities in the semiconductor compound [14].…”

a b s t r a c tSilver-and copper-doped ZnO films were prepared by radio-frequency (RF)-magnetron sputtering on glass and quartz substrates. The influence of dopants content on the microstructural evolution and optical as well as nonlinear optical (NLO) properties were investigated. It has been found that the grain sizes were enlarged with increasing of Ag, Cu dopants amount in ZnO films. The Ag or Cu doping leads to the optical band gap narrowing. Besides, the second-order NLO response of Ag-and Cu-doped ZnO films is lower than that of undoped ZnO film. The second harmonic generation (SHG) efficiency of the ZnO:Ag film was found to be higher than that of the ZnO:Cu film at the similar concentration of dopant. In addition, the decrease of the third harmonic generation (THG) response is observed in ZnO films with increasing of Ag or Cu dopant amount.
