Luminescence of potassium sulphate crystals doped by Eu~(3+) ions

摘要

This paper presents results of the study some spectral-luminescent properties of potassium sulphate crystals activated europium trivalent ions. The observed changes might be connected with the fact of crystals having Eu~(3+) ions and NO_3~- impurity ions. There was a proposition of the possibility of selective creation of impurity centers with the help of using various salts is normal for all the transition metal ions.
