(THE GIST OF PIB) Perovskite Nanocrystal

(FEBRUARY-2025)

Recently, researchers at the Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru have developed an innovative method to minimize anion migration in CsPbX₃ perovskite nanocrystals.

It is a material that has the same crystal structure as the mineral calcium titanium oxide (CaTiO3).
Generally, perovskite compounds have a chemical formula ABX3, where ‘A’ and ‘B’ represent cations, and X is an anion that bonds to both.
A large number of different elements can be combined together to form perovskite structures.
Due to its compositional flexibility, scientists can design perovskite crystals to have a wide variety of physical, optical and electrical characteristics from insulating, semiconducting, metallic and superconducting characteristics.

They have applications in various fields of optoelectronics, including photovoltaic solar cells, photodetectors, light-emitting devices,
Perovskite LEDs, which combine the advantages of OLEDs and QLEDs, have long been considered a promising technology for next-generation lighting.
