摘要
用微波辐射法合成了ＣａＳ∶Ｍｎ２＋橙红色荧光化合物，用ＸＲＤ测定了它们的晶体结构，系统考察了各种不同浓度下的Ｍｎ２＋离子激活剂对发光性能影响．初步认为，微波辐射能使Ｍｎ２＋离子在ＣａＳ基质晶格中均匀扩散，并能提高激发剂的掺入量，阻止Ｍｎ２＋离子的簇集，延缓Ｍｎ２＋离子对的形成．合成方法可得到晶相纯、粒度细小均匀、稳定性高、防潮性好和发光效率高的ＣａＳ∶Ｍｎ２＋荧光体．
A pure crystalline form of CaS and its Mn2+doped phosphors were prepared for the first time by microwave radiation method(MRM). The crystal structures and the luminescent properties of CaS∶Mn2+ were determined. The influence of different Mn2+ concentration on luminescent properties of these phosphors was discussed. It indicates that MRM is a promising method for synthesis of inorganic phosphors.
