Brus equation

The Brus equation can be used to describe the emission energy of quantum dot semiconductor nanocrystals in terms of the band gap energy Egap, Planck's constant h, the radius of the quantum dot r, as well as the effective mass of the excited electron me* and of the excited hole mh*. The Brus equation shows that for a spherical shaped semiconductor nanocrystal, the confinement energy is inversely proportional to the square of the radius of the nanocrystal. The goal of this paper is to investigate this relationship and also ascertain the veracity or otherwise of the confinement energy term. Brus Equation . Spherical Potential Well .
