Abstract

578,313. Luminescent materials. WELLS, A. F. June 24, 1943, No. 10251. [Class 39 (i)] A phosphor particularly for use in cathoderay tubes comprises cadmium sulphate actuated by manganese. It is prepared by mixing crystallised cadmium sulphate with manganese sulphate and with a small quantity of redistilled water, drying the mixture and heating to a temperature of 900‹ C. approximately.
