Abstract
650,459. Luminescent materials. URBACH, F., and PEARLMAN, D. May 2, 1947, No. 11898. Convention date, May 3, 1946. [Class 39 (i)] An infra-red stimulable phosphor comprises calcium or strontium sulphide or both, activated by cerium as dominant and by samarium or bismuth or both as auxiliary activator, a flux, and calcium or strontium sulphate or both in an amount greater than 10 per cent by weight of the flux and 50 per cent by weight of the phosphor. The preparation of the phosphor and its admixture with fluxes, and magnesium oxide filler, is as described in Specification 650,458.
