“…[ 38 ] Grass, orange juice, cocoon silk, persimmons, and numerous other biomass materials rich in saccharide and natural polymers have successfully fabricated into CDs via the treatment of hydrothermal, which was applied in metal ion sensing, bioimaging, and other fields. [ 39 ] The synthesis procedure of solvothermal and hydrothermal method is basically the same, except the solvent is changed from water to ethanol, formamide, dimethylformamide or glycerol. In 2015, Lin's group reported the synthesis of CDs with stable and tunable RGB fluorescence using isomers of phenylenediamines as precursors and ethanol as solvent, with following purification using silica gel column chromatography (Figure 2g ).…”

Seeking clean energy as an alternative to traditional fossil fuels is the inevitable choice to realize the sustainable development of the society. Photocatalytic technique is considered a promising energy conversion approach to store the abundant solar energy into other wieldy energy carriers like chemical energy. Carbon dots, as a class of fascinating carbon nanomaterials, have already become the hotspots in numerous photoelectric researching fields and particularly drawn keen interests as metal-free photocatalysts owing to strong UV-vis optical absorption, tunable energy-level configuration, superior charge transfer ability, excellent physicochemical stability, facile fabrication, low toxicity, and high solubility. In this review, the classification, microstructures, general synthetic methods, optical and photoelectrical properties of carbon dots are systematically summarized. In addition, recent advances of carbon dots based photoinduced reactions including photodegradation, photocatalytic hydrogen generation, CO 2 conversion, N 2 fixation, and photochemical synthesis are highlighted in detail, deep insights into the roles of carbon dots in various systems combining with the photocatalytic mechanisms are provided. Finally, several critical issues remaining in photocatalysis field are also proposed.

“… Defects, including free radicals, nonradiative states, and dangling bonds, on the surface of pristine 0D CNMs negatively affect the fluorescence emission . Defects comprise a diverse range of functional groups, including −OH, −OR, −SH, −SR, −CHO, −COR, −COOH, CONHR, −NH 2 , −NHR, −NR 2 , −NHCOR, and polymer molecules, in which electron-withdrawing groups decrease LUMO levels, ,− while electron-donating moieties raise HOMO levels. Thus, electrons trapped by the formed surface states could facilitate a high yield of radiative recombination and, furthermore, considerably enhance the emission stability and QYs .…”

“…On one hand, carbon sources for the synthesis of carbon dots are very rich, ranging from organic molecules to flowers, trees, fruits, vegetables, grains, animal hair, eggs, milk, and so on. [ 77,79‐82 ] These raw materials for the synthesis of CDs with high fluorescence quantum yield are cheap and nontoxic, which benefit the large‐scale preparation for feeding silkworms. [ 83‐86 ] On the other hand, the properties of CDs are easily adjustable.…”

Comprehensive Summary Fluorescent silk has potential application in many fields such as bioimaging, tissue engineering scaffolds, luminescent marks, and dazzling fabrics. Among the methods to endow natural silk with fluorescent properties, feeding silkworms with fluorescent additives is facile, low‐cost and environment friendly, which has the prospect of large‐scale production. In this paper, we reviewed the research progress for this aim in the past ten years, and summarized the unified characteristics for the substances that can enter the silk gland by digestive tract of silkworms. The advantages and disadvantages of various fluorescent materials for this application are compared in detail. And the future research directions are suggested to overcome the shortcomings of the present research.
