Structural and Optical Analysis of RE³⁺: LiNbO₃ Ceramic Powders

Abstract:

Ferroelectric materials of LiNb0.95RE0.05O3 (RE3+=Eu3+, Sm3+, Dy3+ & Pr3+) have been prepared by a conventional solid state method. From the measurement of excitation and emission spectra of the prominent emission bands, emission performances of these optical materials have been investigated. In addition, structural analysis of these materials has also been carried out based on the data obtained from X-ray diffraction (XRD), Fourier Transform Infra-red (FTIR) spectroscopy, Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDAX). Lifetime measurements have also been carried out for the prominent emission transitions of these ceramic powders.
