摘要

提出了溶胶-凝胶自组装技术制备纳米晶体薄膜。与其他方法相比，这种联合技术更方便、快捷、简单、成本更低。FESEM图像显示Mn掺杂的ZnS呈球形。ZnS:Mn胶体在可见光区具有较高的带隙。此外，还利用光胺(PL)研究了纳米晶体薄膜的光学性质。由于Mn2+的4T1-6A1跃迁，PL光谱显示出蓝色和橙色的发射。

Fabrication of ZnS:Mn nanocrystals by sol gel-self assembly technique

Sol gel-self assembly technique is presented to produce nanocrystals thin films. This combined technique was applied because more convenient, faster, simpler and less costly than others method. FESEM images show that the Mn doped ZnS exhibit the spherical type. The ZnS:Mn colloidal performs the high bandgap in visible region. Furthermore, the optical properties of the nanocrystals thin films are also studied by photolumines (PL). PL spectrum show the blue and orange emission due to 4T1–6A1 of Mn2+ transition.
