Armored with plastic ‘hair’ and silica, new perovskite nanocrystals show more durability

Posted by in category: materials

Perovskite nanocrystals hold promise for improving a wide variety of optoelectronic devices—from lasers to light emitting diodes (LEDs) — but problems with their durability still limit the material’s broad commercial use.

Researchers at the Georgia Institute of Technology have demonstrated a novel approach aimed at addressing the material’s durability problem: encasing the inside a double-layer protection system made from plastic and silica.

In a study published Nov. 29 in the journal Science Advances, the research team describes a multistep process to produce encased perovskite that exhibit strong resistance to degradation in moist environments.
