2. Optical properties of nanocrystal lattices
2.1 Quantum confinement
The first advantage of nanocrystals is that their electronic properties
can be controlled by modulating their geometric properties rather
than the composition of the material.
. For this to be possible, the characteristic
size of the nanocrystal must be smaller than the Bohr radius of the
exciton in the bulk material. The exciton is the quasi-particle made
up of the electron-hole pair photogenerated by absorption, dressed
up with the Coulombic interaction between the two. The Bohr radius
is given by
