Abstract

In this work barium titanate (BT) and strontium titanate (ST) were prepared by Microwave-Assisted Hydrothermal (MAH) method, using a Ti precursor different from those shown in the literature and various concentrations (1, 3 e 6 mol L-1) of KOH mineralizer. As a titanium precursor, an anatase complex with hydrogen peroxide were used. For the precursors of barium and strontium, chlorides were used. The materials resulting from the synthesis processes were characterized in room temperature by different techniques as like: X-Ray Diffraction (XRD), micro-Raman Spectroscopy, UV-Vis, Scanning Electron Microscopy (SEM) and Photoluminescence (PL). The results show that there were differences in crystallinity, morphology, number of phases and photoluminescence depending on the concentration of the mineralizer. (AU)
