摘　　要：采用二次阳极氧化法制备了多孔氧化铝(AAO)模板。利用此AAO模板,采用电化学沉积的方法制备了ZnS∶Mn纳米晶。对AAO模板进行了扫描电子显微镜(SEM)测试。结果显示,AAO模板孔洞分布均匀,孔径基本一致。对ZnS∶Mn纳米晶进行了SEM测试和荧光光谱(PL)测试,SEM测试结果表明,在AAO模板上沉积了一层ZnS∶Mn纳米晶,PL谱结果显示Mn离子成功地掺杂进ZnS。从电负性角度讨论了ZnS∶Mn纳米晶的形成机制。Porous anodic aluminum oxide（AAO）templates were prepared by two-step anodizing oxide method.By making use of the AAO templates,ZnS∶Mn nanoparticles were fabricated with the method of electrochemical deposition.The AAO templates were tested by scanning electron microscope（SEM）.The SEM image shows that the holes of the templates are well-distributed,and the diameter of the holes is uniform.ZnS∶Mn nanoparticles were studied by scanning electron microscope（SEM）and photoluminescence（PL）measurements.The SEM image shows that a layer of ZnS∶Mn nanoparticles has been deposited on AAO templates.PL measurements show that Mn ions had been doped into ZnS.The formation mechanism of ZnS∶Mn nanoparticles are discussed from the angle of electronegativity angle.
