The scientific novelty of the work of scientists from Ural Federal University, Institute of Solid State Chemistry and Geology and Geochemistry of the Ural Branch of the Russian Academy of Sciences lies in the fact that for the first time scientists solved the task of creating zircon with certain spectral properties. To this end, they have worked out the so-called sol-gel method.
It is distinguished by its technological simplicity, controllability of processes and allows synthesizing a larger volume of products with high purity than with other methods.

Materials scientists of Far Eastern Federal University (FEFU), in collaboration with an international research team, have advanced the design of composite ceramic materials (Ce3+:YAG-Al2O3), i.e. solid-state light converters (phosphors) that can be applied in-ground and aerospace technologies. The LED systems based on the developed materials to save 20-30 percent more energy compared to commercial analogues. A related article was published in
Materials Characterization.
Over 15% of the total global electricity production or about $ 450 billion annually spent on lighting. According to the photonics development roadmap run in Russia, the development of LED technology with an efficiency of more than 150 lm/W will allow to release up to 30% of electricity by 2025.
