Brus equation emission energy Δ"E" = "hc"/λ, where c is the speed of light). This is useful for calculating the radius of a quantum dot from experimentally determined parameters. The overall equation is "E", "m"*, and "m"* are unique for each nanocrystal composition. For example, with CdSe nanocrystals: Brus equation The Brus equation can be used to describe the emission energy of quantum dot semiconductor nanocrystals (such as CdSe nanocrystals) in terms of the band gap energy "E", Planck's constant "h", the radius of the quantum dot "r", as well as the effective mass of the excited electron "m"* and of the
Optic equation lens formula: Components of an electrical circuit or electronic circuit can be connected in what is called a series or parallel configuration. For example, the total resistance value "R" of two resistors with resistances "R" and "R" connected in "parallel" follows the optic equation: Similarly, the total inductance "L" of two inductors with inductances "L" and "L" connected in "parallel" is given by: and the total capacitance "C" of two capacitors with capacitances "C" and "C" connected in "series" is as follows: The optic equation of the crossed ladders problem can be applied to folding rectangular paper into three equal
