| 摘 要： | 本文首次用微波辐射法（ＭｉｃｒｏｗａｖｅＲａｄｉａｔｉｏｎＭｅｔｈｏｄ，简称ＭＲＭ）合成了纯的ＳｒＳ基质和ＳｒＳ∶Ｃｅ３＋，Ｋ＋蓝色荧光化合物，用ＸＲＤ测定了它们的晶体结构，系统考察了不同浓度的Ｃｅ３＋离子对发光性能的影响。实验发现，微波辐射能使Ｃｅ３＋在ＳｒＳ基质晶格中均匀扩散，并能提高激活剂的掺入量，阻止Ｃｅ３＋离子的簇集，延缓Ｃｅ３＋离子对的形成，从而能得到晶相纯、粒度均匀和发光效率高的ＳｒＳ∶Ｃｅ３＋，Ｋ＋蓝色荧光体。

| Abstract: | A pure SrS host and SrSCe3 ,K phosphors with blue color were prepared by microwave radiation method (MRM) first time.The crystal structures were determined by XRD.The influence of different Ce3 concentration on luminescent properties of these phosphors was discussed.The experimental results show that MRM compared to the traditional high temperature solid reaction exhibits interesting features,such as rapid reaction without other protective atmosphere,SrSCe3 phosphors with high purity,smaller particles,and higher efficient luminescence with blue color. |
