It could be shown that the hydrogen (H2) treatment of lead iodide (PbI2) is capable to effectively reduce oxidic impurities contained in the source material used for single crystal growth. Comparative experiments of melting PbI2 in H2 and Ar atmosphe

We have developed a procedure to grow lead iodide (PbI 2 , 2H type) crystals using the Czochralski method applying an Ar counter pressure inside a fused silica chamber. The resulting crystal has a length of 3 cm and is free of cracks. Electron backsc

Lead iodide (PbI2) crystals were synthesized with stoichiometric composition and with an excess of iodine or lead. Crystals were further doped by Ag, Au, Ge, and a number of rare-earth elements (RE). The structure of the crystals was analyzed by high

Energy resolution and detection efficiency were compared between new scintillators, lanthanum bromide (LaBr3:Ce) and lanthanum chloride (LaCl3:Ce) with conventional detectors, sodium iodide NaI(Tl) and cadmium zinc telluride (CdZnTe or CZT). The stud

Lead iodide has been recognized as a promising material for room temperature radiation detectors. It has a wide band-gap (∼ 2.3 eV), high atomic numbers (82, 53) and it is environmentally very stable compared to mercuric iodide. Electrical and opti
