【Abstract】 The Lead Iodide (PbI2) crystal is characterized by a large atomic number and a wide band gap, and is one of the promising materials for room temperature nuclear radiation detectors. As a result, a rapid advancement of PbI2 detector has been seen recently. In this paper the combination of PbI2 multi-crystals and the single crystal growth have been investigated, and a yellow PbI2 single crystal has been obtained with size of about 20mm in diameter and 30 mm long.更多还原
