A facile microwave-hydrothermal approach towards highly photoluminescent carbon dots from goose feathers

Author affiliations

Abstract

Biomass such as hair, silk and feathers is regarded as an appealing candidate for the fabrication of heteroatom-doped carbon nanomaterials. In this work, we report a facile and efficient approach to synthesise photoluminescent carbon dots (CDs) from goose feathers by microwave-hydrothermal treatment. These goose feather generated CDs possess a uniform two-dimensional morphology with a diameter of ∼21.5 nm and a height of ∼4.5 nm. Inheriting the heteroatom-rich nature of goose feathers, the resulting CDs contain a large amount of oxygen, nitrogen and sulfur atoms and have a high photoluminescence efficiency of ∼17.1%. Used as label-free photoluminescence probes, the goose feather derived CDs exhibit highly sensitive and selective detection behavior of Fe3+ ions with a low detection limit of 196 nM.
