基于上转换发光的碳量子点制备及应用研究

摘要

CQDs have the characteristics of easy preparation,low toxicity,high chemical inertia,stable fluorescence properties and so on.CQDs and other carbon nanomaterials (such as fullerene,carbon nanotubes and graphene) have attracted the attention of researchers.The synthesis,properties,modification and application of CQDs are discussed in this paper,especially on the Up Conversion Photoluminescence that long wavelength excitation can emit short wavelength.Some implications for the synthesis,modification and application of CQDs based on up conversion photoluminescence are discussed in this paper too.%碳量子点具有易制备、低毒性、化学惰性高、荧光特性稳定等特点,和其他碳纳米材料(如富勒烯、碳纳米管和石墨烯等)一样引起了研究者的广泛关注.本文将从碳量子点的合成、特性、改性和应用等方面进行阐述,并对其受长波长光激发后可发出短波长光的这一上转换发光特性进行重点综述,为今后碳量子点的合成、改性以及应用提供一定的参考.
