Abstract
The paramagnetic resonance spectra of four different infrared stimulable strontium sulfide phosphors have been investigated. The hyperfine spectrum in SrS: Eu,Sm phosphor confirms the existence of divalent europium. The quantum efficiency in this phosphor is less than 1 photon per 10 europium activators. The ground state of europium is split by 0.18 because of spin-orbit coupling in a cubic field. The manganese spectrum in a solid solution of strontium sulfide and selenide is discussed.
