摘要：
PbI2 crystals of various purities were grown using zone-refining technique. Structure of all the crystals was found to be 12R but in few cases in coalescence with 4H. In very pure crystals the phase transition 12R-->2H has been observed under laser light. The findings have been explained on the structural considerations of PbI2.
