Raman spectroscopy and luminescence of mesoporous ZrTiO4 ceramics

Ziconium titanate (ZrTiO4, ZT) is widely used in the electronic industry as high-performance dielectric materials for resonators in microwave region. This oxide also has applications for photo catalysis and for ceramics sensors. ZrTiO4 ceramics having different porosity were prepared by sintering the amorphous powder precursor, synthesized by sol-gel procedure, at different temperatures (1100, 1200, 1300 and 1400 °C). The structure of ceramics was investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) high resolution transmission electron microscopy (HRTEM) and Raman spectroscopy. Luminescence were observed by Raman spectroscopy and studied in details by luminescence spectroscopy.
