摘要：
Lead-iodide-based PbI(2), PbIOH and Pb(3)O(2)I(2) nanocrystals were synthesized by various chemical and mechanochemical solution methods. The nanocrystals were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), dynamic light scattering (DLS), steady-state UV-visible optical absorption and photoluminescence spectroscopy, and by photoluminescence lifetime and quantum efficiency measurements. Scintillation tests were performed on the lead-iodide based material exposed to low-level gamma irradiation.
