在微波场作用下，首次快速合成了球形亚超细尺寸的CaS: Mn2+,Eu2+ 深红色荧光体,SEM 照片显示其粒径为250 400nm,并可观察到纳米粒子的团聚现象,呈现零维纳米材料的特性. 实验结果证实，Mn2+与Eu2+离子间存在着能量传递过程，因而Mn2+对Eu2+的发光具有明显的敏化和增强作用.

CaS:Mn2+, Eu2+ phosphor materials were firstly synthesized in microwave field. The materials synthesized were characterized by XRD、SEM and the fluorescent spectroscopy. The experimental results of XRD and SEM show that the CaS:Mn2+, Eu2+ phosphors possess the crystalline structures with sphere, the mean grain sizes of phosphors are 250400nm. The introduction of Mn2+ into CaS:Eu2+, makes the fluorescence of the CaS:Mn2+, Eu2+ phosphor efficiently enhanced since the energy transfer from Mn2+ into Eu2+ ions. This new synthesis method compared to the traditional high temperature solid reaction exhibits interesting features, such as rapid reactions without H2-H2S protective atmosphere, phosphors with high purity, submicro-scale crystallines, and higher efficient luminescence
