N2 - The purpose of this study is to enhance the red emission intensity and expand the blue excitation band of a (Ca,Sr) 2.82(VO 4) 2:0.12Eu 3+ phosphor for use in copper phthalocyanine (CuPc)-based solar cells and white light-emitting diodes. It was found that substitution of 3% Sr 2 replacing Ca 2 enhanced red emission intensity of Ca 2.82(VO 4) 2:0.12Eu 3+ by 14% under 465-nm by excitation. The Pr 3 co-doping effect was realized when blue excitation intensity of (Ca 0.97Sr 0.03) 2.82(VO 4) 2:0.12Eu 3+, located in the weakest absorption of CuPc, was improved by 126% with the addition of 0.6 mol% Pr 3. The absorption spectrum of CuPc/optimized (Ca 0.9668Sr 0.03) 2.82(VO 4) 2:0.006Pr 3, 0.12Eu 3+ mixtures provided evidence that the (Ca 0.9668Sr 0.03) 2.82(VO 4) 2:0.006Pr 3, 0.12Eu 3+ phosphor could increase the efficiency of incident photons on CuPc-based solar cells. Moreover, the good temperature stability of emission intensity and chromaticity of (Ca 0.9668Sr 0.03) 2.82(VO 4) 2:0.006Pr 3, 0.12Eu 3+ indicated a potential for this phosphor to be applied on the white light-emitting diodes.
