| Abstract: | The matrix K3AlF6 was prepared with a reaction of mixture of solution K2CO3 upon certain solution of Al(OH)3 plus HF (40%), dehydrating at 100 degrees C and annealing for 48 h at 600 degrees C. A series of phosphors for Ce3+, Tb3+ ions in complex fluorides KBF4 and K3AlF6 were synthesized by a solid reaction method. Their excitation and emission spectra were determined, compared with phosphors KAlF4: Ce, Tb, CaF2: Ce, Tb and AlF3: Ce, Tb. The results indicated that Ce3+ could only effectively sensitize Tb3+ in KAlF4 and enhance the emission of Tb3+ significantly. Ce3+ can not effectvely transfer energy to Tb3+ in matrixes CaF2, AlF3, KBF4 and K3AlF6. |
