摘　　要：荧光碳点(CDs)作为一种尺寸小于10 nm的新型碳质纳米材料,因其优异的荧光调谐性、良好的生物相容性以及来源广泛和成本低廉等优点而受到了广泛的研究。此外,由于CDs制备工艺简单、性能优异,在光学传感、能源、生物医学成像、白光发光二极管(WLEDs)等领域均有广泛的应用。近年来,大量的CDs基固态光致发光材料被开发出来并应用于WLEDs领域。基于目前的研究,本文首先对CDs的合成策略进行了简要综述,随后详细介绍了CDs的光致发光机理和实现固态光致发光的方法,并且对CDs应用于WLEDs领域的最新进展进行了总结。最后,讨论了目前CDs研究面临的问题与挑战。Carbon nanomaterials with a size of less than 10 nm,fluorescent carbon dots(CDs),have been extensively investigated,due to their excellent fluorescence tunability,good biocompatibility,wide range of precursors and low cost.Moreover,their simple preparation and excellent performance provide for a wide range of applications in the fields of optical sensing,energy storage,biomedical imaging,and white light-emitting diodes(WLEDs).A large number of solid-state photoluminescent CDs have recently been developed and used in WLEDs.The synthesis strategies of CDs are briefly summarized and their photoluminescence mechanisms are reviewed as well as the recent progress for their use in WLEDs.Finally,prospects for solving the current problems and challenges of CDs for WLEDs are briefly presented and discussed.
