    Lead iodide crystals were synthesized with stoichiometric composition and with an excess of iodine or lead. Some crystals were doped by Ag, Au, Ge and a number of rare-earth elements (RE). HRXRD, EBSD, electrical resistivity, low temperature PL and optical transmittance confirm good crystal quality. Stoichiometric composition or low excess of lead give the best quality crystals. Doping with Ag leads to considerable decrease of electrical resistivity. RE doping generally leads to decrease of optical gap.
