Optical and Structural Characterization of RE3+ (Eu3+, SM3+, Dy3+ & Pr3+): BaTiO3 and LiNbO3 Cerarnic Powders

Ferroelectric materials of Ba0.95RE0.05TiO3 and LiNb0.95RE0.05O3 (RE3+ = Eu3+, Sm3+, Dy3+ and Pr3+) have been prepared by a conventional solid state sintering method. By measuring excitation and emission spectra of the prominent emission bands, luminescence performance of these optical materials has been investigated. In addition, structural analysis of these powder materials has also been carried out by using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, characteristic transition scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX). Lifetime measurements of RE3+ have also been carried out to evaluate emission performance of these ceramic powders.
