(ITMO University) International research team developed a new method of synthesizing miniature light sources. It is based on a special laser producing millions of nanolasers from a perovskite film in a few minutes. Such lasers look like small disks, work at room temperature and have an tunable emission wavelength from 550 to 800 nm. The high speed and good reproducibility of this method make it promising for the industry. The study was published in ACS Nano.
