摘要

采用溶胶凝胶模板法制备红色长余辉发光材料Y

S：Eu

，

（

=Mg，Ca，Sr，Ba），Ti

纳米阵列，利用X射线衍射、扫描电子显微镜和荧光分光光度计、照度计分别研究了不同二价离子掺杂下所合成样品的物相、形貌及发光性能。结果表明：样品排列整齐有序，管径大小统一；不同的二价离子种类没有改变晶体结构和发射峰的位置，但对余辉性能有较大的影响。用324 nm波长光激发样品，由于Eu

的

跃迁，最强的红色发射峰位于626 nm处；不同离子掺杂样品的余辉性能按Ba

、Ca

、Sr

、Mg

的顺序递加，其中二价离子为Mg

时，余辉时间长达287 s（1 mcd/m

），表现出最佳的余辉性能。

Abstract

Red long-lasting phosphor Y

S:Eu

(

=Mg

Ba)

nanoarrays were synthetized by sol-gel template method. The nanoarrays were characterized by powder X-ray diffraction (XRD)

scanning electron microscopy (SEM)

and photoluminescence (PL). The results show that Y

S:Eu

nanotube arrays are highly ordered

regularly arranged and uniform. The doping ions do not change the crystal structure and the situation of emission peaks of phosphors

but have influence on the luminescence properties. Under 324 nm excitation

the strongest red-emission peaks at 626 nm assigned to

transition of Eu

. The afterglow properties of phosphors doped with different divalent ions increase according to the order of Ba

. For the sample doped with Mg

the decay time can last over 287 s (1 mcd/m
