Impurity absorption
WitrynaColored compounds are colored because of the absorption of visible radiation. The color is a result of the compound absorbing a certain color of light, leading to the perception of the ... The solvent, impurities in the solvent, and/or the cuvette glass can absorb light in the selected region. These interferences can be corrected or eliminated ... WitrynaIf the impurity has more electrons, such as a nitrogen impurity (five valence electrons) in a diamond crystal (consisting of carbons, each having four valence electrons), a donor level is formed. Electrons from this level can be excited into the conduction band by the absorption of photons; this occurs only at the blue end of the spectrum in ...
