Silver nanoparticles are nanoparticles of silver whose size varies from 1 nm to 100 nm. They are commonly used in the manufacture of about 200 consumer products, including clothing and cosmetics. While their antibacterial properties are hailed, reckless dumping of these nanoparticles is reported to pollute water and soil due to formation of toxins like silver sulfide.
Researchers from JNCASR have developed an innovative method to activate thermally activated delayed fluorescence (TADF) molecules, by trapping it with light in a “optical cavity”.
