Fluorescent features of CdTe nanorods grafted to graphene oxide through an amidation process

Abstract

We demonstrate a facile synthesis and the fluorescent features of graphene oxide–CdTe hybrid materials. CdTe nanorods have been successfully grafted on to the GO surface through an amidation reaction between acyl chlorides of GO and amino groups of the L-cysteine capped CdTe nanorods. Although fluorescence of the CdTe nanorods can be completely quenched by GO, maintenance and a blue shift of the fluorescence of GO after grafting with CdTe nanorods are discovered due to an incomplete reduction of GO and the basic conditions of the amidation reaction. We believe that the intrinsic optical properties of the GO–CdTe hybrid material may make a promising candidate for graphene- and GO-based materials in optoelectronic applications.
