K2NaAlF6:Ce3+and KAlF4:Ce3+phosphors were synthesized by solid state reaction method at Ar atmosphere. Their structures have been determined and the structure parameters calculated. K2NaA1F6:Ce3+belongs to cubic system
space group Fm3mm
aaaaaaaa=0.8112nm. KAlF4:Ce3+belongs to tetragonal system
space group P4/mmm aaaaaaaaa=0.3556nm
c=0.6147nm. The. spectra of K2NaAlF6 =Ce
3+
and KAlF:Ce
3+
were.measured. According to the characteristic of spectral structure the replaced sites of Ce
