The GdTe polycrystals obtained were powdered and XRD patterns were obtained using a Bruker D8 Advance Diffractometer with Cu-Kα (λ = 1.5406 Å) radiation and characterized based on the Pearson's Crystal Database. Room temperature Raman spectroscopy was done using WITec UHTS Raman Spectrometer (UHTS 300 VIS, Germany) at a laser excitation wavelength of 532 nm. UV-Visible Spectroscopy was used to study the optical absorbance.
