Yellowing of graphene oxide quantum dots is one of its special luminescent properties. Graphene oxide quantum dots can emit not only yellow light, but also various colors of light such as blue, green, and red. Its characteristics include strong photostability, high quantum yield, good biocompatibility, and excellent electron transport properties. Graphene oxide quantum dots emit yellow light and have recognition properties, which can be used to prepare yellow probes similar to fluorescent labels.
The following are the main characteristics and applications of graphene oxide quantum dots emitting yellow light:
High quantum yield and good photostability: Graphene oxide quantum dots exhibit high fluorescence quantum yield during yellowing, as well as the ability to maintain long-term fluorescence emission intensity and stability.
Excellent electron transfer properties: Graphene oxide quantum dots can regulate the surface charge of the substrate through electron transfer, which can be applied in the field of electron transfer devices.
Biomedical applications: The yellowing properties of graphene oxide quantum dots enable them to be used as fluorescent labeled probes for biomedical imaging and drug delivery fields, such as cell imaging and biochemical analysis.
Sensor preparation: The yellowing characteristics of graphene oxide quantum dots can also be used to prepare fluorescent sensors for detecting the presence of heavy metal ions, organic compounds, and other substances.
In summary, the characteristic of yellow light emitted by graphene oxide quantum dots has broad application prospects in fields such as electronic transmission devices, biomedical imaging, fluorescence probes, and fluorescence sensors.

At present, the quantum dots sold by SAT NANO are divided into graphene oxide quantum dots, graphene quantum dots, semiconductor quantum dots, etc. Customers can choose according to their own experimental needs. The preparation methods of graphene quantum dots for sale are divided into bottom-up and top-down methods, with different colors of luminescence available, such as green light, blue light, red light, and white light. Meanwhile, graphene quantum dots with different functional groups can be selected, which is also helpful for later modification and coupling. In addition, there are also nitrogen doped and boron doped graphene quantum dots to choose from.
