METHOD FOR THE PREPARATION OF LANTHANICLE PHOSPHATE GREEN PHOSPHOR

摘要

Green fluorescent having a good coating charcteristic and uniform partical shape and size distribution is made by using one or more of alkali metal phosphate MxPO4(M=one or more element of Li,K,Na) and boric acid as a flux. Thus, 0.05-3 wt.% boric acid or 0.05-10% alkali metal phosphate was calcinated based on the total wt. at 900-1300 deg. C for 3 hr.
