FIELD: semiconductor materials science. SUBSTANCE: used in optoelectronics products operating in the near-infrared region of the spectrum, laser and sensor technique. A method for producing photosensitive lead sulfide films involves deposition from an aqueous solution containing lead (II) salt, sodium citrate, ammonium hydroxide, thiourea, ammonium iodide. In this case, potassium permanganate is additionally introduced into the reaction mixture in an amount of 0.05-7.0 mmol/l. The ammonium iodide content is 0.15-0.20 mol/l. EFFECT: increased photosensitivity of lead sulfide films with respect to visible and infrared radiation. 1 cl, 1 dwg, 1 tbl, 9 ex.
