Consequence of doping mediated strain and the activation energy on the structural and optical properties of ZnO:Cr nanoparticles

Effect of Al-doping on the structure and optical properties of electrospun zinc oxide nanofiber films

“…However, a deviation in the Vegard's law can also be found at the highest Al doping level. Deviation in the Vegard's law has also been reported in case of Mg-doped ZnO thin films and Cr-doped ZnO nanoparticles [34][35][36]. The deviation from the linearity for the former can be attributed to the interstitial incorporation of dopant element Mg in Zn 1Àx Mg x O and to the non-solubility limit of the Mg-precursor in the solutions at higher Mg-concentrations, while it for the latter can be attributed to the interstitial incorporation of dopant element Cr in Zn 1Àx Cr x O and to the fact that at higher concentration Cr is not soluble into ZnO.…”

Comparative study on zinc oxide nanocrystals synthesized by two precipitation methods

“…Various synthesis methods have been used for the preparation of ZnO nanostructures such as vapour-liquid- solid method, reaction vapour deposition, physical vapour deposition, pulsed laser deposition, thermal evaporation and chemical solution routes, like sol-gel, precipitation and hydrothermal methods [10,11]. Among these synthesis routes, chemical solution routes are cost effective, convenient and have general advantages such as super uniformity and high yield of nanocrystals [12].…”

Raman investigations of Zn1−xCoxO nanocrystals: role of starting precursors on vibrational properties

“…We have also recently studied the effects of Cr and Co incorporation in ZnO NPs by Raman spectroscopy. [5,16] It was observed that hexagonal ZnO structure gets distorted with the introduced Cr and Co and a few AMs appear corresponding to the dopant. On the other hand, Yang et al [14] reported that Mn doping in ZnO NPs broadens as well as weakens the E 2 (high) mode of ZnO.…”
