Abstract

This article reports microstructural, morphological, optical, and photoresponse
characteristics of pure and zirconium-doped V2O5 nanorods (Zr:V2O5; Zr at. 1, 3,
5, and 7 wt%) that were synthesized via the wet precipitation method.
Undoubtedly, under experimental conditions, a growth mechanism has been
proposed which explains morphological evolution. The microstructural analysis
confirmed that the prepared samples showed a broad peak consistent with the
V2O5 orthorhombic structure, and the absences of other reflections in this pattern ensure the phase purity. The optimized average crystallite size is determined by using Scherrer’s equation from the most influential (002) peak of
diffraction, which has coincided with those calculated by the TEM micrograph.
SEM images showed agglomerated particles on the surfaces owing to an
increase in the Zr-doping levels. The outcomes of Raman and XPS indicate that
Zr doping can facilitate the generation of V5? and oxygen vacancy. The recorded
UV-DRS spectra reveal the redshifts, and the estimated optical bandgap (Eg)
was decreasing with increasing Zr amount, which is further confirmed by PL
studies. We used the nebulizer spray technique, a cost-effective, sophisticated,
and effective way to formulate an n-ZrxV2O5/p-Si photodetector. The formulated n-ZrxV2O5/p-Si photodetector has good photoconducting behavior.
