Influence of Ni doping on the morphological, structural, optical and electrical properties of CuO thin films deposited via a spray pyrolysis

Green hydrothermally synthesized ultrathin Mg-doped CuO nanoflakes: a structural, electrical and dielectric study

“…13,22,27,30,[35][36][37][38][39] Doping with Ni increases the optical absorption, charge carrier concentration, and photostability of CuO nanostructures. 40 Fe-doped CuO has a slightly higher band gap and electrical conductivity than undoped CuO due to the formation of oxygen vacancies. 41 Moreover, enhanced photosensitive CuO nanostructures have been produced by doping with Cd, 42 Co, 43 Ag, 44 Ba 45 or La, 46 which is crucial for many applications including hydrogen production, photodetection and photocatalysis.…”

Nanostructured CuO Thin-Film-Based Conductometric Sensors for Real-Time Tracking of Sweat Loss

“…When the literature is examined, it is seen that different methods such as chemical bath deposition, spray pyrolysis, evaporation, chemical precipitation method, and successive ionic layer adsorption and reaction (SILAR) are used to synthesize CuO films. SILAR is an easy-to-use, economical, and highly efficient technique in which the thickness and homogeneity of CuO films can be controlled. − …”

Structural, nonlinear optical and antimicrobial properties of sol-gel derived, Fe-doped CuO thin films

“…Since copper has three oxidation states [ 21 ], i.e., Cu + , Cu 2+ , and Cu 3+ , both hole doping, and electron doping mechanisms are possible. By bringing radical changes in the optical, electrical, and magnetic properties of CuO, transition metal doping has recently gained a lot of attention and found outstanding utility in solid-state electronics [ 22 , 23 , 24 , 25 , 26 ]. Ni-doped CuO thin films show higher absorption, charge carrier density, and photostability than pure CuO films [ 20 , 23 , 27 , 28 ].…”

Fe 2+ doping increases Cu 2+ formations and oxygen vacancy in CuO thin films, which increases bandgap slightly while significantly improving conductivity and mobility [ 29 ].…”
