Luminescence of potassium sulphate crystals doped by Eu3+ ions

Abstract

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 Eu3+ions and NO3-impurity ions. There was aproposition of the possibility of selective creation of impurity centers with the help of usingvarious salts is normal for all the transition metal ions.
