摘要： A novel red-emitting phosphor, CaYAl3O7: Eu3+, Sm3+, is synthesized by a combustion method at a low temperature (850℃), and the single phase of CaYAl3O7 is confirmed by powder X-ray diffraction measurements. The photoluminescence property results reveal that the red emission intensity of Eu3+ is strongly dependent on the Sm3+ concentration. Only the Eu3+ luminescence is detected in the Eu3+-Sm3+ co-doped CaYAl3O7 phosphor with 393 nm excitation. However, under the characteristic excitation (402 nm) of Sm3+, not only the Sm3+ emission but also the Eu3+ emission are observed. A possible mechanism of the energy transfer between Sm3+ and Eu3+ is investigated in detail.
