| 中文摘要 | an orange-emitting phosphor was obtained via efficient ce3+-mn2+ and eu2+-mn2+ energy transfers in la-9.33(sio4)(6)o-2, and has been developed for solid state uv/near-uv white lighting applications. the luminescence properties and energy transfer from ce3+ to mn2+ and eu2+ to mn2+ are investigated. the la-9.33(sio4)(6)o-2:ce3+, mn2+ phosphor shows a blue emission centered at 380 and an orange emission peaking at 590 nm, which could be ascribed to the allowed 5d -> 4f transition of the ce3+ ion and the t-4(1g)(4g) -> (6)a(1g)(6s) transition of the mn2+ ion, respectively. upon excitation at 365 nm, the eu2+, mn2+ co-doped la-9.33(sio4)(6)o-2 phosphor exhibits the eu2+ green emission band and the mn2+ orange emission band. non-radiative transitions between the ce3+/eu2+ and mn2+ ions in the la-9.33(sio4)(6)o-2 host are both demonstrated to be attributable to dipole-quadrupole interactions. the intensity ratio of the mn2+ emission bands can be enhanced through the increase of the mn2+ content, which is attributed to the efficient energy transfer from ce3+/eu2+ to mn2+, and the corresponding chromaticity coordinates (0.50, 0.38), (0.51, 0.46) were obtained with the la-9.33(sio4)(6)o-2:ce3+, mn2+ and la-9.33(sio4)(6)o-2:eu2+, mn2+ samples. results indicated that the as-prepared phosphors might have promising applications in white-light leds as an orange-emitting phosphor. |
