Influence of Cu doping on the local electronic and magnetic properties of ZnO nanostructures

Abstract

Cu doping in ZnO modifies the electronic structure and the hybridization between Cu and O orbitals results in RTFM due to formation of BMPs.

Rapid green-synthesis of TiO2 nanoparticles for therapeutic applications

“…11 has been obtained by plotting the VSM data after subtracting the diamagnetic contribution thereby resulting solely in ferromagnetic contribution. 30 We can see from the plot that the weak ferromagnetic behaviour of T1 and T3 are almost similar and overlapping whereas T2 shows slightly more ferromagnetic character. In order to use the NPs for targeted drug delivery, their ferromagnetic character can be of great help.…”

Insights into ZnO-based doped porous nanocrystal frameworks

“…Related XAS interpretation was also given on the bullet-like morphologies of Cu-doped ZnO crystal synthesized by the sol–gel route. 75 The shoulder at 9000.5 eV in all the doped films is due to the substitution of Cu in the Zn lattice. Also, the likenesses of the oscillations and magnitude of the Zn K-edge k 3 -weighted EXAFS spectra for both bare ZnO and doped films show the substitution of Zn by Cu without distortion.…”

Mn‐Dependent Morphology and Structure of SnS2 Nanosheets and the Photocatalytic Performance

“…It is found that the peak intensity SnS 2 changes obviously and decreases with increasing the Mn contents (Figure 1a), indicating the introduction of Mn affects the size and crystallinity of ST materials, [24] that may be related to the formation of thin and wrinkle structure. Notably, magnified peak of (001) plane reveal that the peaks at 15.03° of Mn‐doped ST materials shift to the low diffraction angle and there are different deviations for different Mn‐doping dosages compare with pure SnS 2 (Figure 2b), implying Mn ion is intercalated into SnS 2 crystal lattice and it leads to the lattice shrinkage resulting from small ion radius of Mn [25] . Additionally, no diffraction peak of Mn species is found and it is because of low content of Mn that is below the detection limit of XRD diffractometer.…”

“…Notably, magnified peak of (001) plane reveal that the peaks at 15.03°of Mn-doped ST materials shift to the low diffraction angle and there are different deviations for different Mn-doping dosages compare with pure SnS 2 (Figure 2b), implying Mn ion is intercalated into SnS 2 crystal lattice and it leads to the lattice shrinkage resulting from small ion radius of Mn. [25] Additionally, no diffraction peak of Mn species is found and it is because of low content of Mn that is below the detection limit of XRD diffractometer. To estimate the average crystallite sizes, Scherrer equation is used to calculate based on XRD results.…”
