| 中文摘要 | ce3+ and eu2+ singly doped and ce3+/eu2+-codoped ca7mg(sio4)(4) phosphors are synthesized by the conventional solid state reaction. the ce3+ activated sample exhibits intense blue emission under 350 nm excitation, the composition-optimized ca7mg(sio4)(4):4% ce3+ shows better color purity than the commercial blue phosphor, bamgal10o17:eu2+ (bam:eu2+) and exhibits superior external quantum efficiency (65%). the ca7mg(sio4)4:eu2+ powder shows a broad emission band in the wavelength range of 400-600 nm with a maximum at about 500 nm. the strong excitation bands of the ca7mg(sio4)(4):eu2+ in the wavelength range of 250-450 nm are favorable properties for applications as light-emitting-diode conversion phosphors. furthermore, the energy transfer from the ce3+ to eu2+ ions is observed in the codoped samples, the resonance-type energy transfer is determined to be due to the dipole-dipole interaction mechanism and the critical distance is obtained through the spectral overlap approach and concentration quenching method. |
