Abstract

This paper investigates the energy transfer of Sm3+→Eu 3+ in (Ca, Ba)3(VO4)2:Sm 3+, Eu3+ phosphors. The multipolar mechanism of energy transfer (Sm3+→Eu3+) was found to be dipole-quadrupole. The energy transfer efficiency and possibility were calculated according to the emission intensity and lifetime of the energy donor Sm3+. With the addition of 2 mol% Sm3+ as the sensitizer, the integrated emission intensity of red (Ca0.901Ba 0.099)2.82(VO4)2:0.12Eu 3+ phosphor under 465 nm excitation was enhanced by 35%. The sensitization effect is realized when the excitation peak of (Ca 0.901Ba0.099)2.82(VO4) 2:0.12Eu3+ was extended from 465 to 405 nm. The (Ca, Ba)3(VO4)2:Sm3+, Eu3+ phosphors can down-convert near-UV and blue wavelength photons, located in the weakest absorption of copper phthalocyanine (CuPc), to red-emitting photons in the optimal absorption of CuPc. These results imply that the optimized (Ca 0.89Ba0.099)2.82(VO4) 2:0.02Sm3+, 0.12Eu3+ phosphor is a candidate for application to CuPc-based solar cells and the white light-emitting diode with a blue chip.
