Abstract

AbstractBarium molybdate (BaMoO4) is one of the materials used extensively in electronic and optical devices. Although there are many synthesis methods in the literature, a route for facile synthesis of nano‐BaMoO4 has been ignored. In this study, BaMoO4 nanoparticles were produced by the co‐precipitation method at room temperature within a short time. The effects of ammonia solutions and surfactants on the morphology of the particles were investigated. Various properties of these materials were characterized by XRD, SEM‐EDX, elemental mapping, TEM, and UV‐Vis analysis methods. Also, the crystal structure parameters and the compatibility of these values with the theoretical calculations were determined by Rietveld refinement. From the HR‐TEM image, the interplanar spacing was calculated as 3.2 Å. It was determined from these analyses that BaMoO4 particles with optical band gaps varying between 3.80 and 3.95 eV were produced in nano and micrometer sizes. It has been demonstrated by this study that the pH of the synthesis solution and the type of surfactant have significant effects on the morphological and optical properties of the materials.
