TL;DR: Zn1−xNixO with 0.2 nanoparticles (NPs) were prepared by co-precipitation with subsequent annealing at 500°C for 2.h as mentioned in this paper.

TL;DR: In this article, pure and Mn 2+ doped ZnO nanoparticles were prepared by co-precipitation method followed by drying at 200 ÂC. X-ray diffraction analysis revealed the formation of hexagonal wurtzite for pure and ndoped ZNO samples with a minor secondary phase.

TL;DR: In this article, a non-ionic surfactant, Tween-80, was used during the preparation process of Zn1-xCoxO nanoparticles and X-ray diffraction analysis showed the formation of wurtzite ZnO phase nanostructures.

TL;DR: In this article, the formation of hexagonal wurtzite structure for all dopant levels without any impurity was confirmed by X-ray diffraction analysis, which indicated a decrease in the value of the band gap with increasing Fe doping concentration and the elemental composition of Zn, Fe and O quantitatively obtained from EDAX analysis confirmed the purity of the as-prepared nanopowders and that the chemical composition is close to the starting stoichiometries.

TL;DR: In order to reduce the band gap, transition metal dopants have been incorporated into ZnO so that it changes the photo electrochemical properties and the effect and variation of CBM and VBM in DSSC parameter are discussed.
