Abstract

Strontium molybdate particles (SrMoO4) with uniform shapes have applications in various fields such as phosphors, optical fibers, scintillators, magnets, sensors, and catalysts. SrMoO4 were prepared by Microwave Assisted Hydrothermal (MAH) method with variations in applied experimental parameters. The effect of the applied synthesis methodology and experimental parameters on the morphology, particle size, sample uniformity and optical properties of the SrMoO4 were studied. In this study, was observed that the microwave radiation favors an organization of material and that this organization can be changed with a capping agent, which provokes alterations in morphology, a disorder-order degree of material and variations of band gap energy. This study indicates that surface defect states favor an alteration in properties of the PL emission. The control of a surface state, the particle size and morphology can be a form to modify the property in accordance with optics characteristics the desired one. (AU)
