Next generation lighting - Perovskite Nanocrystal

Lighting consumes 20% of global electricity and advancements in lighting technology have significantly improved energy efficiency.

From the incandescent and fluorescent lamps of the past to the invention of LEDs in the 1960s

A pivotal breakthrough occurred in 1993, when Shuji Nakamura and his team members developed high brightness blue LEDs, enabling energy efficient white LEDs, which got them 2014 Nobel Prize in Physics. LEDs lead the market in efficiency and lifespan.

Other types of LEDs:

1. OLED (Organic LEDs)
   • offer vibrant colors
   • thin and flexible
   • costly and shorter lifespan
2. QLED (Quantum LEDs)
   • precise color and durability
   • toxic and resource scarcity
3. micro / mini LED
   • high brightness and stability
   • limited in application
   • high production cost

Perovskite LEDs, which combine the advantages of OLEDs and QLEDs, have long been considered a promising technology for next-generation lighting.

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,
