Analysis of the concentration dependence of KCl : Ag optical absorption by random-walk method
The absorption spectra of KCl:Ag single crystals with varied concentration of Ag+ ions are analyzed by the multivariable random-walk method. It is shown that intracenter absorption and charge-transfer with formation of perturbed-impurity centers of different coordination are responsible for the absorption event within the spectral range 6.35-5.3 eV.
