In a major breakthrough, scientists have discovered a way to create infrared quantum dots using a cost-effective and simple fabrication process. Quantum dots are nanocrystals that have unique properties that make them useful for a variety of applications, including LEDs, solar cells, and medical imaging. The new process, developed by a team of researchers from the University of Tokyo, makes it possible to create quantum dots that emit light in the infrared spectrum, something that was not possible before.

The team used a technique called “solvent-selective etching” to create the quantum dots. This method involves using a solvent to selectively etch away parts of a material, leaving behind only the desired components. The team was able to create quantum dots that emitted light in the infrared range, a range of light that is difficult to produce with traditional materials.

The implications of this research are far-reaching. Infrared quantum dots can be used in a variety of applications, from medical imaging to LED lighting. In the future, this technology may even be used to create new types of optical devices that are more efficient and cost-effective.
