| Resumo | |
Ag2CrO4 microcrystals were synthesized by means of the coprecipitation method without the use of a surfactant under three different conditions. On the basis of the theoretical and experimental results, we describe the relationship among the structural order/disorder effects, morphology, and photoluminescence of the Ag2CrO4 microcrystals. The experimental results were correlated with the theoretical findings for a deeper understanding of the relationship between the electronic structure, morphology, and photoluminescence properties. First principles computational studies were used to calculate the geometries of bulk Ag2CrO4 and its low-index (001), (011), (110), (010), (111), and (100) facets based on a slab model. A good agreement between the experimental and the theoretical morphologies was found by varying the ratio of the superficial energy values. (AU) | |
