Description
技术领域
本发明涉及一种荧光碳点溶液的制备，特别是涉及一种具有超高量子产率金属离子掺杂碳点溶液的制备方法。
背景技术
碳点(Carbon Dots,CDs)是一种直径小于10纳米的零维碳纳米材料。CDs因为其荧光稳定高、耐光漂白且无光闪烁，激发波长和发射波长可调谐，原料廉价，生物相容性好，毒性低等优异的性能而备受广大研究者的关注。因此，CDs可以作为半导体量子点(如CdSe、CdTe、CuInS2、CsPbBr3等)和有机染料的替代物被应用于生物标记、生物成像、催化、防伪和光电器件等领域。
CDs的快速发展令人感到兴奋。但是，迄今为止人们制备的大部分CDs的量子产率位于2％～60％且光学稳定性一般，如2017年，北京工业大学环境与能源工程学院孙再成教授团队以柠檬酸与尿素为前驱体，二甲基甲酰胺为溶剂，通过溶剂热法制备了一系列CDs，这些CDs的量子产率介于10％～55％之间。有许多重要的应用领域，例如在太阳能聚光器，LED和光学显示薄膜，需要同时具有高PLQY和超高光学稳定性的CDs。因此，如何解决此问题已成为CDs在这些领域中应用的重中之重。
发明内容
本发明的目的是为了克服现有荧光CDs存在的缺点和不足，提供一种合成方法简单有效，原料廉价易得，反应条件温和，具有超高量子产率与超高稳定性的金属离子掺杂碳点溶液的制备方法。在365nm紫外灯照射下，合成出的CDs溶液分别呈现明亮的黄色荧光。
为了实现上述目的，本发明提供的技术方案如下：一种金属离子掺杂碳点溶液的制备方法，其特征在于，将柠檬酸、尿素与金属盐加入到溶剂中，混合搅拌，然后置于反应釜中，升温反应，反应结束，冷却至室温，即可得到具有超高量子产率与超高光学稳定性金属离子掺杂碳点溶液；所述金属盐为氯化铟、醋酸铟、氯化锰、醋酸锰、醋酸锌、硬脂酸锌、氯化镉、醋酸镉或硬脂酸镉中任意一种或几种。
优选所述的溶剂为甲苯、氯仿或四氯化碳中任意一种或几种。
优选所述的升温反应的反应温度为160～240℃，反应时间为3～24时。
优选柠檬酸与金属盐的摩尔比为1：(1～4)；柠檬酸与尿素的摩尔比为1：(1～8)。
优选所得金属离子掺杂碳点的量子产率为60％～92％。
所述的一种具有超高量子产率金属离子掺杂CDs的制备方法，其特征在于：所得金属离子掺杂CDs具有激发不依赖的性质，其最佳发射波长位于460～570nm。
所得金属离子掺杂碳点在紫外光连续照射24小时情况下无荧光淬灭现象。
有益效果：
本发明制备的金属离子掺杂CDs制备方法简单，材料成本低廉。此外，该CDs在掺杂离子之后量子产率得到提升，荧光颜色红移且荧光稳定性大幅提升，金属离子掺杂CDs在溶剂中分散性良好，这大大地拓宽了CDs的应用领域。
