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

“…1(h), D decreases with increasing the Mg content. Besides, the dislocation density ( δ ) and internal strain ( ε ) were calculated using the following relations: 53 …”

The Enhanced Photocatalytic Performance of Pr Doped Cu2O Under Visible Light

“…According to the UV‐Vis DRS and the band gap equation (2), [31] the ( αhv ) 2 ‐ hv fitting curves for Pr : Cu 2 O with different Pr doping amounts (0, 1, 3, and 5 mol %) were obtained. $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr \alpha hv={\rm A}(hv\hbox{-}{\rm Eg}){^{{\rm n}/2}}\hfill\cr}}$$$ …”

“…Moreover, the absorption edge shifts slightly to higher wavelengths when the Pr doping increases from 0 % to 3 % and to shorter wavelengths when the Pr doping increases from 3 % to 5 %. [30] According to the UV-Vis DRS and the band gap equation ( 2), [31] the (αhv) 2 -hv fitting curves for Pr : Cu 2 O with different Pr doping amounts (0, 1, 3, and 5 mol %) were obtained.…”

Copper oxide nanoparticles doped with lanthanum, magnesium and manganese: optical and structural characterization

“…For this reason, researchers have tried to improve the electrical and optical properties of Cu 2 O by incorporating various transition metals such as cobalt [35], iron [35,36], manganese (Mn) [22,35,37–40] and nickel [35]. In addition, the incorporation of other elements such as aluminium [41], cerium [42], lithium [43–45], magnesium (Mg) [1,43,46–48], silver [41], sodium [44], samarium [49], titanium [44] and zinc [42,43,50] has also been evaluated.…”

“…There are many methods to obtain doped Cu 2 O nanostructures, such as biosynthesis [51,52], chemical vapour deposition [46,47], electrodeposition [22], hydrothermal synthesis [37], pulsed laser deposition [40], solvothermal synthesis [38,39] and spray pyrolysis [46,48]. In addition to these methods, the chemical displacement or substitution technique is an interesting but little-explored alternative.…”
