Individual quantum dots can be created from two-dimensional electron or hole gases present in remotely doped quantum wells or semiconductor heterostructures called lateral quantum dots. The sample surface is coated with a thin layer of resist and a lateral pattern is then defined in the resist by electron beam lithography .
In order to survive the competition with conventional semiconductor quantum dots, a high quantum yield should be achieved. Although a good example of CQDs with ~80% quantum yield was synthesized, [ 33 ] most of the quantum dots synthesized have a quantum yield below 10% so far. [ 7 ]

The 2023 Nobel Prize in chemistry has been awarded to a trio of scientists who worked to discover and develop quantum dots, used in LED lights and TV screens, as well as by surgeons when removing ...
Another application of this technique involves using Zinc Sulfide quantum dots to treat industrial waste water. [18] Indium An alternative to the heavy metal quantum dots are quantum dots that contain Indium. One example is the use of CuInS2 quantum dots as fluorescent labels that emit light in the near infrared region of the visible spectrum. [19]
Typical substances used to synthesize quantum dots are cadmium (Cd) and selenium (Se). [22] [24] For example, when the electrons of two nanometer CdSe quantum dots relax after excitation, blue light is emitted. Similarly, red light is emitted in four nanometer CdSe quantum dots. [25] [22]
Graphene quantum dots (GQDs) are graphene nanoparticles with a size less than 100 nm. Due to their exceptional properties such as low toxicity, stable photoluminescence , chemical stability and pronounced quantum confinement effect, GQDs are considered as a novel material for biological, opto-electronics, energy and environmental applications.
