Abstract
- We analyze the optical characteristics of crystals within the framework of a model representation that presupposes the entry of the background impurity of iron ions in two valence states, Fe<superscript>3+</superscript> and Fe<superscript>2+</superscript>, into regular lattice nodes. The spectral manifestation of intrinsic defects of vacancy-type structure depending on the conditions of crystal growth and heat treatment is comprehensively investigated. With allowance for the specific features of the technology applied, we have tested the technique suggested in scientific periodicals for bleaching ZnWO<subscript>4</subscript> and CdWO<subscript>4</subscript> crystals by doping with nonisovalent ions, in particular, with Sb and Ag impurities.
