Resumo: | In this study, Ba1−xZnxMoO4 (x = 0, 0.25, 0.5, 0.75 and 1) microspheres were the first time described in the literature the by ultrasonic spray pyrolysis method. Powders were characterized by X-ray diffraction (XRD), scanning electronic microscopy (SEM-FEG) and UV–visible and Photoluminescence (PL) spectroscopies. The XRD patterns showed that the samples with x = 0 and x = 1 displayed pure tetragonal and triclinic structures, respectively. On the other hand, samples with x = 0.25, 0.5 and 0.75 revealed the formation of tetragonal/ triclinic heterojunction structure. The SEM-FEG images showed that the Ba1−xZnxMoO4 particles present the spherical morphology with the decrease of particle sizes when the value of “x” increase. The gap energies vary between 4.56 eV and 4.17 eV, being influenced by the degree of structural order-disorder. The PL emission spectra of the samples showed a broad band behavior with emission intensity predominant in the orange-red region and of a lower intensity in the blue-green region. The chromaticity coordinates x and y showed that the samples with x ≤ 0.75 present emission in orange, while the samples with x = 1 showed emission in white |
