[29] [30] [31] For example, silicon and germanium quantum dots have been synthesized by using nonthermal plasma. The size, shape, surface and composition of quantum dots can all be controlled in nonthermal plasma. [32] [33] Doping that seems quite challenging for quantum dots has also been realized in plasma synthesis.
Spin-cast quantum dot solar cell built by the Sargent Group at the University of Toronto. The metal disks on the front surface are the electrical connections to the layers below. A quantum dot solar cell (QDSC) is a solar cell design that uses quantum dots as the captivating photovoltaic material.
Another application of this technique involves using Zinc Sulfide quantum dots to treat industrial waste water. [19] 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. [20]
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, [ 34 ] most of the quantum dots synthesized have a quantum yield below 10% so far. [ 7 ]
Typically, the size of the silicon quantum dots is defined by controlling material synthesis. For example, silicon quantum dot size can be controlled by the reaction temperature during thermal disproportionation of silsesquioxanes. [1] Similarly, the plasma residence time in non-thermal plasma methods is a key factor. [2]
Superconducting quantum computing is a branch of solid state physics and quantum computing that implements superconducting electronic circuits using superconducting qubits as artificial atoms, or quantum dots.

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]
