| 中文摘要 | a novel white-light-emitting phosphor ca9lu(po4)7:eu2+,mn2+ has been prepared by solid-state reaction. the photoluminescence properties indicate that there is an efficient energy transfer from the eu2+ to mn2+ ions via a dipole-quadrupole reaction. the obtained phosphor exhibits a strong excitation band between 250 and 430 nm, matching well with the dominant emission band of a uv light-emitting-diode (led) chip. upon excitation of uv light, white light is realized by combining a broad blue-green emission band at 480 nm and a red emission band at 645 nm attributed to the eu2+ and mn2+ ions. the energy-transfer efficiency and critical distance were also calculated. furthermore, the phosphors can generate lights from blue-green through white and eventually to red by properly tuning the relative ratio of the eu2+ to mn2+ ions through the principle of energy transfer. preliminary studies showed that the phosphor might be promising as a single-phased white-light-emitting phosphor for a uv white-light led. |
