“…Barium molybdates belonging to the transition metal oxide family are among the interesting materials due to their structural and luminescent properties. Previous research has established that BaMoO 4 particles are synthesized by various fabrication methods such as co‐precipitation, hydrothermal, solvothermal, and solid‐state [6–24] . It is understood from these studies that the morphological and crystallinity properties of materials are significantly affected by the synthesis methods, precursor materials, surfactants, and solvents used in the production of nanomaterials.…”

Barium 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.

Currently, data‐driven approaches for exploring novel materials are garnering significant attention with the expectation of accelerating material development cycles and understanding materials from various aspects. This short article presents a supervised prediction model for the emission intensity ratio of 5D0–7F2 and 5D0–7F1 transition of Eu3+ ions, called an “asymmetry ratio”, which determines the color purity of the red region of Eu3+ photoluminescence in perovskite phosphors. The model is developed using a dataset of 296 samples and 203 descriptors for Eu3+‐doped perovskite. The accuracy of the prediction model trained by the dataset is statistically evaluated, which validates its sufficiently high prediction performance. Furthermore, the prediction model's performance is properly assessed by synthesizing a Eu3+‐doped NaLaInNbO6 compound, which is unknown as a red phosphor, and by comparing the experimental asymmetry ratio for this compound with that predicted by the predictor, which exhibits satisfactory agreement.
