Abstract

ABSTRACT: The present study briefs the structural and optical properties of Gd doped BaZr0.05 Ti0.95 O3 ceramic synthesized via solid-state reaction (SSR) technique. The X-Ray diffraction (XRD) study reveals the formation of single phase of Gd modified BaZr0.05 Ti0.95 O3 ceramic. The Fourier transform infrared (FTIR) spectra are also presented in support of structural properties. The optical band-gap obtained from the UV-visible study, decreases with an increase in the Gd content. The photoluminescence study shows a broad hump around 560 nm. The studied compositions reveal the major contribution of shallow holes as compared to deep holes within the band-gap.
