摘要

采用高温固相反应法合成了一系列Dy

、Sm

单掺杂和共掺杂铝方柱石发光材料，详细地研究了Dy

、Sm

掺杂对铝方柱石的结构和发光性质的影响。XRD结果表明Dy

、Sm

离子单掺杂和共掺杂样品均形成了单相的铝方柱石结构化合物，并没有改变基质的晶体结构。发光光谱表明，通过调节Dy

、Sm

离子的掺杂比例，发光颜色可实现从黄色到黄白色的可控调节。此外，发射和激发光谱表明，Dy

与Sm

离子之间存在有效的光谱重叠，暗示着Dy

的能量传递。荧光寿命衰减结果进一步证实Dy

与Sm

离子之间是一种无辐射共振能量传递方式。

Abstract

A series of Dy

co-doped Ca

A1[AlSiO

] phosphors were synthesized by the solid-state reaction. The crystal structure and luminescent properties of the samples were investigated by XRD

PL spectra and lifetime decay. XRD results show that the as-prepared phosphors are single-phase melilite compounds. Dy and Sm codoped do not vary the crystal structure of melilite. The PL spectra results show that the emission color can be tuned from yellow-emitting to warm-white lighting by changing the ratio of Dy

to Sm

. In addition

the PL and PLE results demonstrate that there is a significant energy transfer from Dy

to Sm

. The lifetime decay results further verified that the energy-transfer mode of Dy

is attributed to the nonradiative energy-transfer.
