Abstract
Inorganic mesoporous materials have been attracting increasing attention during the past decade. In the present work, photoluminescent Ag2S nanospheres with mesoporous structures were prepared by assembling Ag2S nanoparticles with opposite charges in aqueous phase. Without structure-directing templates, mesoporous Ag2S with well-ordered face-centered cubic superlattice structures and high specific surface area was obtained. The mesoporous Ag2S nanospheres had the same crystal phase as their precursors Ag2S nanoparticles. Different from their near-infrared emitting precursors, the mesoporous Ag2S nanospheres exhibited cyan emission under ultraviolet excitation. The large number of sulfur-related defects existing in the mesostructures is most likely responsible for the photoluminescence. This work provides new insights into fabricating photoluminescent mesostructured materials via scale-up strategy.
