摘要

利用微反应器提高碳点sp3-C杂化度，实现了碳点的有效收窄和蓝移光致发光。所得CDs发射出以345 nm为中心的紫外（UV） PL，全宽半峰宽（FWHM）为54 nm，蓝移超过100 nm，与传统溶剂热法制备的CDs相比，FWHM缩小了近一半。

Narrowing and blue-shifting photoluminescence of carbon dots by enhancing sp3-C hybridization using a microreactor†

Effectively narrowing and blue-shifting photoluminescence (PL) of carbon dots (CDs) through enhancing their sp³-C hybridization degree by using a microreactor are achieved. The resulting CDs emit ultraviolet (UV) PL centered at 345 nm with a full width at half maximum (FWHM) of 54 nm, with blue-shift of over 100 nm and FWHM narrowed by nearly half in comparison with that of the CDs prepared by using the traditional solvothermal method.
