Abstract
PURPOSE: To prepare an Eu-doped halo-phosphate fluorescent material which emits fluorescent light having mainly blue spectrum, in high efficiency and stimmulation purity.
CONSTITUTION: A fluorescent material of formula (MII is Zn, Mg, Ca, or Ba; MIII is Al, Y, La, or Gd; M' is Ca, Sr, or Ba; X is halogen; z is 0.0015W0.20; x is 0W0.999; y is 0W0.999; x+y+z≤1) is prepared by mixing the above elements as halides, wherein the ratio of a/b is 0.3W1.2 and the amount of the halogen is in excess of the stoichiometric amount (pref. 1.25W3.5 times), and calcining the mixture in a reducing atmosphere (pref. at 900W1300°C).
