Abstract

In this study, nanocrystalline Zn1-xGdx (x=0.0 and 0.03) samples were synthesised via the Sol-gel combustion process. An array of analytical techniques was employed to examine the prepared samples to determine their different physical features. For both pristine and Gd-doped samples, the crystal symmetry is hexagonal with the P63mc space group which is verified via the Rietveld refinement analysis of X-ray diffraction (XRD) data. The atoms’ bond length Zn-O and bond angle Zn-O-Zn/Gd are measured. The pure and Gd-doped materials surface morphology is studied by SEM (scanning electron microscopy) images at 5,000x magnification. EDS (energy dispersive x-ray spectroscopy) verifies the elemental compositions with the proper elemental stoichiometry. The crystallite size value varies from 18 to 25 nm for pristine and Gd-doped samples. FTIR (Fourier transform infrared) Spectra give details regarding the various modes of vibration related to the functional groups that exist in the samples. To examine their optical characteristics, the diffuse reflectance spectrum of UV visible is applied. Using Tauc’s relation to compute the bandgap, it is discovered that Gd doping causes it to drop from 3.18 eV to 2.89 eV.
