- •
Ce3+ and/or Eu2+ doped Ca2AlSi3O2N5(CASON) phosphors are synthesized via solid state reaction.
- •
The energy transfer from Ce3+ to Eu2+ have been confirmed by the analysis of intensity and decay time.
- •
The incorporation of Ce3+–CASON:Eu2+ significantly increases the emission intensity by ∼45% of the original value.
