Multifunctional Carbon Dots for Highly Luminescent Orange-Emissive Cellulose Based Composite Phosphor Construction and Plant Tissue Imaging

Abstract

A new class of carbon dots (CDs) grafted cellulose hybrid phosphors has been prepared in a facile and fast process. The reddish-orange emissive CDs can be effectively dispersed in cellulose matrices through hydrogen binding, thus highly efficient orange-emissive CD-based phosphors were successfully obtained with a quantum yield of 44%. Moreover, the affinity of CDs for binding cellulose provides them the feasibility for fluorescent mapping of cellulosic plant cell walls. Several model plant tissues have been employed to investigate the pathway of CDs. Confocal analysis demonstrated that plant tissues can readily absorb CDs from aqueous solution and bind them with cellulose-rich structure. These studies may open up new avenues for the exploration of CDs in long-wavelength emissive solid-state lighting and plant tissue imaging.
