Luminescence of potassium sulphate crystals activated by Sn2+ ions

The aim of this paper is to study some spectral-luminescent properties of sulphates activated by tin ions. The paper presents the photoluminescence excitation spectra of K2SO4-Sn2+ crystal. In this spectrum, peaks are observed at 240 nm and 260 nm. In the long-wavelength wing, the emission band has...

Description
Summary:The aim of this paper is to study some spectral-luminescent properties of sulphates activated by tin ions. The paper presents the photoluminescence excitation spectra of K2SO4-Sn2+ crystal. In this spectrum, peaks are observed at 240 nm and 260 nm. In the long-wavelength wing, the emission band has a "shoulder" indicating the presence of the second emission band. Thus, the presence of two bands of photoluminescence excitation suggests that K2SO4 formed two types of the impurity luminescence center differing in the immediate surroundings.
