In this work, nitrogen and sulfur-doped carbon nanodots (CNDs) have been synthesized from ethylenediamine-N,N′-diacetic acid and 2,2′-(ethylenedithio)diacetic acid, respectively. The method used in this work features the use of “single” molec

Colloidal metal-halide perovskite quantum dots (QDs) with a dimension less than the exciton Bohr diameter DB (quantum size regime) emerged as promising light emitters due to their spectrally narrow light, facile color tuning, and high photoluminescen

In this work, nitrogen-rich carbon nanodots (CNDs) are prepared by the emulsion-templated carbonization of polyacrylamide. The formation mechanism and chemical structure are investigated by infrared, nuclear magnetic resonance, and X-ray photoelectro

Chemically derived graphene quantum dots (GQDs) to date have showed very broad emission linewidth due to many kinds of chemical bondings with different energy levels, which significantly degrades the color purity and color tunability. Here, we show t

Carbon nanodots (C-dots) are a kind of fluorescent carbon nanomaterials, composed of polyaromatic carbon domains surrounded by amorphous carbon frames and have attracted a great deal of attention because of their interesting properties. There are sti

Size-controlled soft-template synthesis of carbon nanodots (CNDs) as novel photoactive materials is reported. The size of the CNDs can be controlled by regulating the amount of an emulsifier. As the size increases, the CNDs exhibit blue-shifted photo

We report electrical measurements of films of carbon quantum dots (CQDs) that serve as the channels of field-effects transistors (FETs). To investigate the dependence of the field-effect mobility on ligand length, colloidal CQDs are synthesized and l

Carbon nanodots (CND) have recently attracted tremendous attention for a variety of optical and optoelectronic applications. Although many attempts have been made to obtain high-quality CND in high yield, there have been few endeavors to regulate its

Highly luminescent nearly monodisperse carbon quantum dots (CQDs) are synthesized by facile emulsion-templated carbonization of low cost and non toxic carbohydrates excluding the size selection procedure. The present method is further combined with i
