An oxide composition of 3:1 (Hf1-xZrx)O2:P2O5, and having the empirical formula (Hf1-xZrx)3 P2O11, where x is in the range of about 0 to 0.5, is an effective luminescent material for use in x-ray intensifying screens, and also an effective luminescent material host for Eu+2 blue emmissions. The luminescent material is obtained in essentially single crystalline large particles when prepared in the presence of a magnesium fluoride flux. |
