| 中文摘要 | 采用原位共沉淀与气氛还原氮化相结合的方法,在1100℃下制备出Ca2AlSi3O_2N5:Sm~(3+)。使用X射线衍射仪(XRD)、场发射扫描电子显微镜(FE-SEM)以及稳态瞬态荧光光谱仪(PL)对合成产物的结构、微观形貌和发光特性进行了研究。在287nm紫外光激发下,测得Ca2AlSi3O_2N5:Sm~(3+)的发射光谱为1个多峰宽谱,主峰分别为602nm(4G5/2→6H7/2)和650nm(4G5/2→6H9/2)。研究了Sm~(3+)掺杂浓度对Ca2AlSi3O_2N5:Sm~(3+)红光荧 |
| 英文摘要 | Ca2AlSi3O2N5:Sm3+ phosphor was prepared by a combination of in-situ co-precipitation method with a gas-reduction-nitridation method at 1100 degrees C. Its structure and luminescent properties were investigated with XRD and PL. The emission spectrum of Ca2AlSi3O2N5:Sm3+ shows several pesks at 602 nm ((4)G(5/2) -> H-6(7/2)), and 650 nm ((4)G(5/2) -> H-6(9/2)) under 287 nm excitation. The effect of the doping concentration of Sm3+ activator on the luminescence properties was studied. It is found that the luminescence intensity increases with increasing of Sm3+ doping concentration within limits, and then decreases. The photoluminescence intensity reaches the highest when the Sm3+ doping concentration is 1 mol%. |
