The number of CdSe nanoparticles of 2.0 nm that can fit across human hair with diameter of 50 μm should be determined. Concept introduction: The quantum dots of any solids can be defined as the semiconductor particles that have size in nanoparticle range. Since size of nanoparticle is intermediate between the bulk solids and atoms thus the spacing between electronic energy also has intermediate value between large for atoms and continuous band for bulk solids. Therefore, spacing between bands depends on size of nanoparticle. These different energy gaps can create valence band and conduction band and can give different colors on transition.
