How Does Quantum Confinement Alter Material Properties?
When the size of a material is reduced to the nanoscale, the electron's motion is restricted, and it can only occupy specific energy levels. This leads to a shift in the band gap of the material. For instance, in quantum dots, the band gap increases as the size of the dot decreases, resulting in changes to the material's optical and electronic properties. This size-dependent behavior allows for the tuning of material properties through precise control of particle size.
