• ITMO Researchers Describe Carbon Dot Structure, Discover Red Emission Amplification Method

  Fluorescent carbon nanoparticles, also known as carbon dots, were first described in the early ‘00s. But even today, scientists around the globe still have not reached a consensus on their inner structure and emission process. Carbon dots have a great deal of potential applications due to their biocompatibility with the human body and the ease and low cost of their production as compared to semiconductor quantum dots. Researchers from ITMO University have published two research papers in which they put forth their answers to the burning questions about carbon dots.

• Scientists Propose a Fully Optical Method for Near-Field Reshaping and Enhancement in Hybrid Metal-Dielectric Oligomers

  Scientists from ITMO University in collaboration with researchers from Saint Petersburg Academic University have developed a fully optical method that allows to reconfigure the properties of hybrid metal-dielectric oligomers in the near field. This offers a simpler and cheaper alternative to the existing methods of working with such structures. The use of metal-dielectric oligomers has a lot of potential for developing new data recording devices, as well as in sensor science. The research was published in Laser & Photonics Reviews.
