Abstract

. We present the results of X-ray diffraction studies for undoped and Fe-doped single crystals of lead iodide in the concentration range 0.01–0.25 at. %. PbI 2 and PbI 2 :Fe crystals are obtained by crystallization from a vapour phase in a closed system under over-stoichiometric iodine-vapour pressure. Morphology of the crystals has been analyzed by a scanning electron microscopy. The effect of iron doping on the low-temperature ( T = 4.2 K) photoluminescence spectra of lead iodide has been elucidated.
