Abstract: In this work, we present a general hybrid solvothermal methodology to synthesise perovskite BaMO3 nanocrystals with tunable sizes and long-time stability. In contrast with commonly reported methodologies, the combination of aqueous sol-gel and solvothermal treatments not only allowed the successfully production of these particles but also a high tunable control of their size and homogeneity. By using this approximation, we evidence the role of water in the hydrolytic step as the key parameter to tune the size of the final nanocrystals.
In addition we also demonstration the nanocrystals effectiveness to enhance the superconducting properties once the nanocrystals are mixed into YBa2Cu3O7 matrix. Given the novelty and potential relevance of our hybrid method in a deep range of nanoscaled systems.
