Abstract: | Bismuth titanate (Bi4(TiO4)3) ceramic powders have been synthesized by using a solid state reaction method. Prominently intense blue emission at 480 nm has been measured with an excitation at 418 nm. The reason for the observance of such a blue emission from this ceramic powder has been explained. The phase formation has been investigated by X-ray diffraction analysis (XRD). The morphology and composition of the ceramic powders have been studied from the measurement of SEM and EDS profiles. FTIR and Raman spectra have also been recorded to analyze the presence of functional groups and Raman active modes in the Bi4(TiO4)3 ceramic powders. The sintering temperature has been optimized to be 1100 °C based on the measured TG–DTA profiles of the as prepared material. Besides these, dielectric properties of ceramic powder in the frequency range of 200 Hz–3 MHz at 300 K have also been carried out. |
