Abstract

711,547. Luminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 9, 1951 [Aug. 11, 1950], No, 18781 (51. Class 39(1) A luminescent material has the formula of 3 Ca 3 (PO 3 ) 2 v MX 2 wherein v is a fraction or one M is either cadmium or zinc, and X is a chloride or fluoride or a mixture thereof, the activators being antimony and manganese. The antimony is present in not more than four per cent and the manganese from one half to three per cent of the halophosphate. Calcium phosphate and the metal halide are mixed in apatite proportions and fired at 1100-1300‹C.
