Abstract

Highly hierarchical structures of silver indium tungsten oxide (AgIn(WO4)2) mesocrystals can be rationally fabricated via the microwave-assisted synthesis method by tuning the initial concentrations of the precursors. Photoluminescence spectra of hierarchical AgIn(WO4)2 mesocrystals were measured to investigate the correlation between the morphology, pressure, and temperature and their luminescence properties. The materials showed interesting white emission when excited by visible light of wavelength 460 nm. AgIn(WO4)2 materials having different morphologies displayed notable differences in photogenerated emission performance. The emission was strongly correlated with the surface nanostructures of outgrowths, with larger amounts of outgrowths leading to stronger emission intensities. The pressure- and temperature-dependent photoluminescence properties of these materials have also been investigated under hydrostatic pressures up to 16 GPa at room temperature and in the temperature range from 10 to 300 K.
