摘要
目前,市面上常见的防伪材料单一,表现形式受限,无法满足新型防伪功能的需要.本文采用化学键连接的方式将碳点材料与长余辉材料结合,研发出复合纳米防伪材料(Zn2GeO4-CDs),研究了其发光特性并应用于防伪油墨,结果表明,这种复合材料具有多色发光、发光效率高、表现形式多样、合成技术成熟等特色,使用不同激发光照射时会发出不同颜色的光,材料的掺杂比不同时也会发出不同颜色的光,可以有效实现防伪,实现数据多层保护的功能,应用前景十分广阔.
Abstract
Currently,the common anti-counterfeiting materials on the market are single,with limited forms of expression,and cannot meet the needs of new anti-counterfeiting functions.This article combines carbon dot materials with long afterglow materials through chemical bonding to develop composite nano anti-counterfeiting materials(Zn2 GeO4 CDs).Its luminescent properties were studied and applied to anti-counterfeiting inks.The results show that this composite material has the characteristics of multi-color luminescence,high luminescence efficiency,diverse expression forms,and mature synthesis technology.When different excitation lights are used,different colors of light will be emitted.The doping ratio of the material is different,and it will also emit different colors of light,which can effectively achieve anti-counterfeiting and multi-layer data protection.The application prospects are very broad.
