Semiconductor nanoparticles exhibit effects of quantum confinement of electrons and holes in dictating optical and electronic properties. One can thus tune the band gap by changing the particle size. As the Optical properties are strongly dependent on particle size, a particle size distribution is expected to cause inhomogeneous broadening of optical spectra. Nanocrystalline materials exhibit a variety of properties that are different and often considerably improved in comparison with bulk materials. These include increase strength, enhanced diffusivity, improved ductility/ toughness, reduced ...
