Abstract

711,560. Luminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 9, 1951 [Aug. 11, 1950], No. 17243/53. Divided out of 711,547. Class 39(1) A luminescent material has the formula 3 Ca 3 (PO 1 ) 2 v, MgX 2 wherein v is a fraction or 1 and X is either chlorine or fluorine or both and is activated by antimony (up to 4 per cent) and manganese (0.5-3 per cent). It may be made by mixing together in apatite proportions dicalcium hydrogen phosphate and the halide of magnesium together with antimony and manganese and firing for one half to two hours at 1100-1300‹C, preferably one hour at 1170‹C.
