Aggregation-based abrupt crystallization from amorphous Ag2S to Ag2S nanocrystals.
Abrupt crystallization from ∼2-5 nm (amorphous) to ∼12-15 nm (crystalline) was observed in hydrothermal coarsening of Ag2S. The desorption behavior of capping ligands could be associated with the aggregation and fusion of amorphous particles into crystals.
