一步水热法制备锰掺杂型硫化锌量子点复合纸

One Step Synthesis of Composite Paper with Mn Doped ZnS Quantum Dots(QDs)by Hydrothermal Method

以滤纸为复合纸的基底,通过绿色一步水热法将硫化锌量子点(ZnS QDs)和Mn元素掺杂的硫化锌量子点(Mn∶ZnS QDs)与滤纸复合,制得量子点复合纸。复合纸中的ZnS QDs和Mn∶ZnS QDs尺寸均一,晶体结构完整,均匀分布于滤纸纤维表面。当激发光在280 nm^380 nm范围时,ZnS QDs和Mn∶ZnS QDs的复合纸能够产生荧光效应,而Mn:ZnS QDs的复合纸在600 nm-710 nm的激发光作用下能够产生新的荧光现象。

Using filter paper as the base of composite paper,zinc sulfide quantum dots(ZnS QDs)and Mn element doped zinc sulfide quantum dots(Mn∶ZnS QDs)were compounded with filter paper by green one-step hydrothermal method.The size of ZnS QDs and Mn∶ZnS QDs in the composite paper were uniform,the crystal structure was complete,and they were evenly distributed on the surface of filter paper fiber.The composite paper of ZnS QDs and Mn∶ZnS QDs produced fluorescence effect when the excitation light was in the range of 280~380 nm,while the composite paper of Mn∶ZnS QDs produced new fluorescence phenomenon under the excitation light of 600~710 nm.
