Resumo

This work elucidates the morphology-photoluminescence (PL) emission relationships, based on experimental and calculated results, on beta-Ag2MoO4 samples synthesized by microwave-assisted hydrothermal method. It was shown that the solvent (water and ammonia) and temperature (120, 130, 140, and 150 degrees C) play a crucial role in the morphology and PL emissions. A crystal structure model, composed by the local coordination of both Ag and Mo atoms at bulk and exposed surfaces, was built, and the possible mechanism along the synthesis progress was proposed and analyzed. This study provides an idea for the preparation and development of beta-Ag2MoO4 based materials with desirable properties. (AU)
