Quantum dots are manmade nanoparticles of
semiconducting material comprising only a few thousand atoms.
Because of the small number of atoms, a quantum dot’s properties
lie between those of single atoms or molecules and bulk material
with a huge number of atoms. By changing the nanoparticles’ size
and shape, it is possible to fine-tune their electronic and optical
properties—how electrons bond and move through the material, and
how light is absorbed and emitted by it.
Use of perovskite will be a key feature of the next
generation of electronic appliances
