摘要

利用液相沉淀法制备得到了不同形貌的纳米及微米SrB

O：Eu

，对产品进行了EDS、XRD、IR、SEM等表征。结果表明反应时间对产品的结晶度、形貌、粒径有较大的影响。此外，研究了产品的光致发光性能，结果发现所有产品的最强发射峰都位于

=615 nm处，为红色发光；产品的发光随反应时间的增加而增强，而红橙比随反应时间的增加先增大后减小。当反应时间为48 h时，产品在激发波长为391 nm和250 nm时的发光强度相当，但在391 nm时红橙比更高，是一种良好的近紫外激发红色发光材料。

Abstract

Nano and mirco SrB

O:Eu

with different morphologies were prepared by precipitation method

and they were characterized by EDS

XRD

SEM

their luminescence properties were also studied. The results show that the reaction time has great impacts on the crystallinity

morphology and particle size of the samples. The strongest emission peaks of the samples are all located at 615 nm

exhibiting red emission. The luminous intensity is enhanced with the increasing of reaction time

while the ratio of red to orange increases firstly and then decreases. For the sample with reaction time of 48 h

the emission intensities are similar when it is excited by 391 nm or 250 nm

but the ratio of red to orange excited by 391 nm is higher than that excited by 250 nm

indicating that SrB

O:Eu

is a good near-ultraviolet excited red luminescent material.
