Material processing has become essential for the proper control, tuning and consequent application of
the properties of micro/nanoparticles. In this case, we report herein the capability of the microwaveassisted hydrothermal (MAH) method to prepare the SrTiO3 compound, as a case study of inorganic
compounds. Analyses conducted by X-ray diffraction, X-ray photoelectron and X-ray absorption
spectroscopies confirmed that the MAH route enables the formation of pristine SrTiO3. The results
indicated that the combination of thermal and non-thermal effects during the MAH treatment provides
ideal conditions for an efficient and rapid synthesis of pristine SrTiO3 mesocrystals. Scanning electron
microscopy images revealed a cube-like morphology (of ca. 1 mm) formed via a self-assembly process,
influenced by the MAH time. Additionally, photoluminescence measurements revealed a broad blue
emission related to intrinsic defects, which decreased with the MAH synthesis time. [-]
