Ca2Al2SiO7 (CAS) doped with Eu3+ and Dy3+ was successfully synthesised with the solid-phase reaction method, in which the sample was sintered at 1,280 °C for one hour. The energy-transfer phenomenon from Dy3+ to Eu3+ was observed in the CAS matrix. The optimal doping concentration of Dy3+ and Eu3+ is 1.5 and 1% mol. In addition, the energy-transfer mechanism, CIE colour coordinate, and CCT colour temperature of CAS/Dy3+/Eu3+ were also presented and discussed.
