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
ISO 3166-2:MC ISO 3166-2:MC ISO 3166-2:MC is the entry for Monaco in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1. Currently for Monaco, ISO 3166-2 codes are defined for 17 quarters. Each code consists of two parts, separated by a hyphen. The first part is , the ISO 3166-1 alpha-2 code of Monaco. The second part is two letters. Subdivision names are listed as in the ISO 3166-2 standard published by the ISO
