“…The size distribution of BCDs prepared from egg white was well controlled, and the quantum yield was greatly improved. Dried shrimp and pipe tobacco were also used as carbon sources to prepare N‐doped BCDs. Of course, in addition to the N‐doped, there is also S‐doped in heteroatom doping.…”

Carbon dots (CDs) have received much attention due to their superior properties including water solubility, low toxicity, biocompatibility, small size, fluorescence, and ease of modification. The use of a more environmentally friendly method to prepare high‐quality CDs is still an urgent question waiting for solve. The use of renewable, inexpensive, and green biomass resources not only meets the urgent need for large‐scale synthesis biomass CDs (BCDs), but also promotes the development of sustainable applications. In this article, we summarize the representative methods for synthesizing BCDs in green and simple ways using biomass as a carbon source, including hydrothermal carbonization, and microwave, pyrolysis. The prepared BCDs have a uniform particle size distribution and a relatively high throughput, which provide a method to scale up industrial production. Moreover, the integration of specific optical properties, that is, tunable photoluminescence and up‐photoluminescence, has led to remarkable use in bioimaging, sensing, and drug delivery. But the current review is not particularly comprehensive for BCDs. Therefore, we now provide a review focusing on the synthesis, properties, and recent advances in BCDs in biosensing, bioimaging, optoelectronics, and catalytic applications.

“…These functional groups are vary according to the raw materials which are used in the synthetic procedures [7].The CQDs have attracted much the attention from researchers due to: First of all, being of their eco-friendly, high biocompatible, chemically stable, low toxicity and highly soluble in water [8][9]. Secondly, the CQDs are characterized by the electronic and optical properties such as electron acceptor or donor, high photoluminescence, that have made it an important material in applications ,electronic, optical and sensing devices, bioimage, delivery of drug [10][11][12][13][14].Finally, the CQDs can be prepared using fast, low-cost method, and by from like natural raw materials or organic waste [15][16]. Indeed, this properties made CQDs are a good alternative to conventional semiconductors (CdS, CdSe, ZnS, etc.…”

The carbon quantum dots (CQDs) were prepared by using an easy and economic onepot method. The starting materials are the ascorbic acid as a carbon source and copper acetate as a catalyst to accelerate the reaction. The structural and optical properties of the CQDs are studied by UV-VIS spectrophotometer and photoluminescence (PL) measurements, transmission electron microscope (TEM), X-ray diffraction (XRD) and Fourier transform-infrared spectroscopy (FTIR). The excitation wavelength and the pH-dependent of PL properties was investigated also. The results show that the CQDs have strong absorption peak in the UV-region. The PL is the excitation wavelength dependent. The PL of CQDs decreases upon lowering the pH value of the solutions and the PL peaks shifted to the shorter wavelength. The average size of the CQDs is 4 nm from the TEM measurements.
