St. Pete team improves composites’ optical properties

15 Jul '20
Researchers at ITMO University in St. Petersburg have improved targeted treatment technology for nanoporous glass based composites with silver and copper added. Results have been published in English in Nanomaterials.

This is expected to give the team a plasmonic structure with highly (and accurately) predictable optical properties.

All composite materials have the high potential to be used in optical instruments such as lasers, lidars, sensors, lenses, waveguides and other applications where a light signal must be processed. The scientists pin much hope on glass with metal nanoparticles added.

“Such materials could be used as optical filters,” said Pavel Varlamov, an engineer at ITMO’s Department of Laser Photonics and Optoelectronics.

Depending on what metal ions are added to the glass, a resultant composite could control a very specific part of the spectrum, as required.
