CBSE Class 12-science Answered

what does colour center mean?
Asked by parathabateaanda | 30 Jun, 2010, 12:00: AM
answered-by-expert Expert Answer

Colour centre is defect in the regular spacing of atoms within a solid that absorbs visible light of a particular colour or infrared or ultraviolet radiation, thus lending a characteristic colour to the solid. For example the colour centre called F-centre results from the absence of a negatively charged ion from a particular point in an ionic solid.
