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

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 perovskite inside a double-layer protection system made from plastic and silica.

In a study published today (November 29, 2019) in the journal Science Advances, the research team describes a multistep process to produce encased perovskite nanocrystals that exhibit strong resistance to degradation in moist environments.
