Abstract:
A method of forming a phosphor composition is disclosed. The method includes mixing co-precipitated yttrium-europium oxalate with an inorganic flux material to form an oxalate-flux mixture; and heating the oxalate-flux mixture at a temperature in a range from about 800° C. to about 1400° C., to form the phosphor composition. The phosphor has a general formula of (Y1-x-yAyEux)2O3 with 0
