Abstract
PURPOSE: To obtain a stable calcium halophosphate phosphor having high luminescence, by sintering a raw material blend at low temperature to reduce loss of Sb and Cl and to form apatite structure, followed by sintering at high temperature.
CONSTITUTION: A raw material blend of calcium halophosphate phosphor is sintered at 750W800°C so that not less than 70 wt.% of β-Ca2P2O7 is made into apatite structure. This resulting material is sintered at enough temperature to fluorescent, e.g., at 1000W1200°C.
