Scientists obtain new optical materials with nanodiamond inclusions

25 october 2024

A team from eight scientific institutes in Russia has developed new materials for fine optics, the press service of the Ministry of Education and Science reported.

The new material is based on the silicon dioxide aerogel, a porous ultralight material embedded which ultra-fine nanodiamonds.

"Scientists have obtained new transparent composite materials containing nanocrystalline diamonds evenly distributed in a silicon dioxide aerogel matrix. The concentration of nanodiamonds in the composites was 0.01% - 1%, which made it possible to change the optical characteristics of the materials in a controlled manner. Such composites are promising functional materials for optics and optoelectronics," the press service noted.

Chemists use diamond nanocrystals obtained by detonation method. Such nanodiamonds are considered very promising materials for many fields, which include, for example, quantum photonics, high-precision environmental sensing, biovisualization, targeted drug delivery, and chemical catalysis among others, TASS reports.
