Abstract

Microcrystalline Pb2P2S6 powder was synthesized via a traditional melting salt method. The nanostructured Pb2P2S6 powder was further synthesized by a high-speed ball milling technique. The optical properties of the Pb2P2S6 powder show a size-dependence, with the band gap ranging from 2.56 eV to 2.88).
