中文摘要	a series of single-component red/white-emitting cascalsio6:ce3+,tb3+,mn2+ phosphors have been synthesized by a solid-state reaction. it is observed that cascalsio6:ce3+,tb3+ phosphors exhibit two dominating bands situated at 380 and 542 nm, originating from the allowed 5d -> 4f transition of the ce3+ ion and the d-5(4) -> f-7(j) = (j = 6, 5, 4, 3) transition of the tb3+ ion, respectively. as for cascalsio6:ce3+,mn2+, our results indicate that mn2+ may occupy not only a ca2+ site to generate an orange emission [mn2+(i)] at 590 nm but also a sc3+ site to generate a red emission [mn2+(ii)] at 670 nm. both energy transfers from ce3+ to tb3+ and from ce3+ to mn2+ in the cascalsio6 host are investigated and have been demonstrated to be of the resonant type via a dipole dipole mechanism. by proper tuning of the relative composition of tb3+/mn2+, white light can also be achieved upon excitation of uv light, indicating that the developed phosphor may potentially be used as a single-component red/white-emitting phosphor for uv-light-emitting diodes.
