Paper Abstract

Lead-iodide-based nanocrystals were synthesized by dissolution of commercial lead iodide powder in a coordinating solvent, tetrahydrofuran, and subsequent re-crystallization after an optimum addition of methanol. The nanocrystals were characterized by transmission electron microscopy, scanning electron microscopy, energy dispersive spectroscopy (EDS), steady state UV-visible optical absorption and photoluminescence spectroscopy, and by photoluminescence lifetime and quantum efficiency measurements. The radiation hardness of the synthesized material was tested using a 137Cs gamma source. Scintillation was observed from the lead-iodide based material exposed to low-level gamma irradiation.
