ITMO Researchers Use Hybrid Crystal to Enable Simultaneous Grayscale and Color Direct Laser Writing
With the new material suggested by ITMO physicists, it will be possible to embed grayscale images into color ones during direct laser writing. The researchers were the first to use metal-organic frameworks for the purpose; these are optically transparent materials that can transform laser radiation. When subjected to it, the material’s structure changes, with color defects formed inside. Each such defect has a unique scattering spectrum, making metal-organic frameworks useful in producing uncloneable anti-counterfeit trademarks. The material is described in a paper published in Advanced Functional Materials.

New Discovery Makes Cheap, Compact Lasers Possible
Researchers from ITMO have demonstrated a novel technique for generation of laser radiation that utilizes perovskite metasurfaces. The solution will pave the way for next-gen lasers that are less than 100 nm thick and require significantly less energy. The invention can be incorporated into compact photonic chips for light control or used as an intense light source in medicine (e.g., for tissue or blood diagnostics), materials processing, astronomy, and other fields. The results of this study were published in the journal Advanced Functional Materials.

ITMO Researchers Develop Special Ink For Anti-Counterfeiting Protection
Scientists from ITMO University, Bauman Moscow State Technical University, and the University of Toronto have developed a gel ink that emits light when exposed to monochromatic radiation of various wavelengths. This makes it possible to create complex images when applying tags to products – the scientists believe that the level of anti-counterfeiting protection offered by their invention is much higher than that of the existing counterparts. The research received support from a Russian Science Foundation and the Ministry of Science and Higher Education grant.

Scientists Propose a Carbon Dot-Based Method for Increasing the Efficiency of Solar Cells and LED
An international group of scientists, including some from ITMO University, has proposed a method that allows for significantly increasing the efficiency of solar cells and light-emitting diodes. The scientists managed to achieve this result by augmenting the auxiliary layers of the devices responsible for electron transport rather than working with the main active layer. The work has been published in the journal Advanced Functional Materials.
