Abstract
THE superiority of lead selenide photoconductive cells over lead sulphide cells and over purely thermal infra-red detectors in the 3–4 µ region has already been described1,2. The preparation of these sensitive layers has always been by an evaporation method3,4 analogous to that previously used for lead sulphide5. Chemical deposition processes6 7 for the preparation of lead sulphide cells have been further developed by us, until comparable sensitivity at room temperature and greater sensitivity at low temperatures than these obtained with evaporated cells are available.
