Abstract
This paper presents an experimental study of the effect of doping with manganese on the vapor phase growth of lead(II) iodide crystals in a closed system and their properties. The manganese concentration in the grown crystals and the mass transport rate in the PbI2–I2 system are determined by the Mn concentration in the growth charge and the temperature of the source zone. We have obtained single crystals of the following morphological types: elongated ribbons, ribbons with sharp ends, plates, and their combinations and intergrowths. Doping with manganese has been shown to influence low-temperature (T = 5 K) photoluminescence spectra of PbI2.
