Preparation and Photoluminescence Properties of ZnO/BaTiO_3 Nanocomposite System
Source abstract
Abstract
The ZnO/BaTiO_3 nanocomposite system was prepared by a sol-gel method. The particle size, structure and phases of the nanocomposite were studied by XRD and TEM. In addition, enhanced photoluminescence of the nanocomposite under 370nm light excitation was observed at room temperature. The blue-green emission peak induced by oxygen vacancies of nano-ZnO particles, has blue-shift or red-shift with different heat-treatment temperatures, the blue-shift is assigned to quantum size effect, and the red-shift is attributed to the high dielectric environment effects of the BaTiO3 matrix.
