Quantum dots for a number of years used for displays and solar panels. For example, in Sony displays . The essence of their work is that they can absorb a sufficiently wide spectrum of radiation, while at the same time themselves emit a pure colors in a narrow range.
Developers of the company together with Quantum Materials Rice University have developed a technology for creating quantum dots in a tetrapod - a geometric shape with four symmetrically diverging branches. Core size of a quantum 3D-point, as long processes can be controlled during manufacture. Thus the output we get the quantum dots with unique emission spectrum. Such points can be incorporated into the packaging of goods in the case and processor chips in 3D-printers, and so forth. In this signature can only be read with a special scanner, which is also being developed by Quantum Materials together with a number of companies and research organizations. 3D quantum dots also help in creating solutions for the safe operation of electronic devices and computers. They can serve as tokens and used to change passwords.
According to estimates Allied Market Research, market protection against counterfeiting today brings its participants a year to $ 57 billion in 2020, its value will reach $ 143 billion, with annual growth of 14%. Only pharmaceuticals and food in 2015 will require protected against counterfeiting packaging for $ 82 billion By the way, if you build such identification technology in 3D-printers, it can then be easily calculate what equipment was issued .
