Abstract

The structure of nanoparticles that undergo a surface-driven structural transformation was analyzed. The room temperature transformation was found to take place in 3 nm ZnS nanoparticles in methanol following the addition of water. A large increase in the crystallinity associated with water addition was observed using experimental wide angle x-ray scattering (WAXS), x-ray absorption near edge structure (XANES), and extended x-ray absorption fine structure (EXAFS) spectroscopy measurements. The structural disorder was indicated to be partitioned between interior and surface regions more strongly than predicted by molecular dynamics simulation.
