摘要(Abstract):
水凝胶因其具有优异的可拉伸性、出色的韧性以及与皮肤的紧密贴合而备受关注.然而,对其发光性能的研究鲜有报道.因此,本工作利用碳点(CD)作为掺杂剂采用一锅自由基聚合法制备出了CD-PAM/CMC发光水凝胶.同时,通过浸渍法将Eu~(3+)进一步引入到CD-PAM/CMC发光水凝胶内部,实现了对水凝胶发光性能的可控调节.结果表明:CD的引入不仅能够提高水凝胶的强度而且使水凝胶的荧光强度高于CD溶液的本身;研究进一步发现,当CD的质量分数达到0.2%时,其荧光性能达到最佳.另外,通过调节CD与Eu~(3+)的比例能够实现对水凝胶发光颜色的可控调节,同时有希望合出能够发白光的水凝胶.为未来冷光源的开发与应用提供一个思路.
