Investigation of the morphological, optical and antimicrobial properties of Nd-doped ZnO nanoparticles using Hemidesmus indicus (L.) R. Br. Root extracts

Abstract

In the current study, we present a low-cost, novel, and straightforward method for the biopreparation of zinc oxide nanoparticles (ZnO NPs) and neodymium (Nd³⁺) doped ZnO NPs using extracts of Hemidesmus indicus (H. indicus) (L.) R. Br. root like a sustainable reducing as well as coating agent. Rietveld’s analysis of the XRD data showed that ZnO and Nd³⁺ doped ZnO NPs have a hexagonal wurtzite crystalline level. The morphological representation of synthesized NPs was analyzed by FESEM and chemical composition by EDAX. The different vibrational frequencies were assigned for the FT-IR spectra. The Optical behaviour of the prepared NPs be present studies by UV–visible spectroscopy. Moreover, this study concludes the antimicrobial efficiency of the synthesized NPs opposed to standard and clinical strains of Staphylococcus aureus (gram-positive) and Klebsiella pneumoniae (gram-negative) bacterial strains using the well diffusion method.
