Abstract
A review is given on studies of different types of colour centres in calcium fluoride crystals. Production, analysis and application of some colour centres like F and F aggregate centres, M A centre, oxygen centre, colloidal centre, and photochromic centre are discussed. The results of ESR, ENDOR, Magnetic Circular Dichroism (MCD). Raman spectroscopy, positron annihilation spectroscopy are reviewed. Irradiation effects on the colourability of pure and doped calcium fluoride crystals are also discussed.Keywords
