An international team of scientists that includes researchers from ITMO University has developed a new composite material based on perovskite nanocrystals for the purpose of creating miniature light sources with improved output capacity. The introduction of perovskite nanocrystals into porous glass microparticles made it possible to increase their operating time by almost three times, and the subsequent coating of these particles with polymers - to increase the stability of their optical properties when underwater, which is especially important for the purposes of creating light sources for application in biological media. The results have been published in ChemNanoMat.Perovskite nanocrystals are some of the most researched objects in modern materials science. They have excellent optical properties, such as the purity and brightness of emitted light, which makes them appealing for use in modern laser systems. At the same time, perovskites are unstable in the air, when interacting...
