Detailed calculations have been performed of multiphonon relaxation rates of optical excitations in Nd-doped LiYF 4 and Pr-doped CsCdBr 3 crystals in the frameworks of the exchange charge model of the crystal fields and rigid ion harmonic models of lattice dynamics. It is shown that the empirical en
## Abstract Colour changes of YAG crystals doped with rare earth ions and annealed in hydrogen, oxygen, vacuum or argon are described. The influence of UV irradiation is also given. Some crystals were further doped with Ca, Sr, Ba, or Cr, respectively. Yellow or brown colouring of the crystals is a
