What are Perovskites?

Perovskite Nanocrystal Latest News

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.

About Perovskite Nanocrystal

• 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.

 Applications of Perovskite Nanocrystal

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

Perovskite Nanocrystal FAQs

Q1: What are the applications of perovskite crystal structure?

Ans: Probably the dominant applications of perovskites are in microelectronics and telecommunications,

Q2: What are the four nano materials?

Ans: There are four main types of intentionally produced nanomaterials: carbon-based, metal-based, dendrimers, and nanocomposites

Q3: What is the difference between single crystal and nanocrystal?

Ans: A nano-crystal composed of poly-crystal or a single crystal. A single crystal has no grain boundary and a nano-crystal has grain or no grain boundary.
