Abstract

The effect of modifying the host composition on the photoluminescent properties of the ir stimulable phosphor system SrBaS : (Eu, Sm) was investigated. Spectral measurements (stimulated emission, fluorescent emission, excitation, and IR stimulation) were made on nine separate host compositions. The lattice constant, ionicity, and lattice strain affect Stark splitting of the rare earth excited states. While large shifts in the ir stimulated emission and fluorescence wavelengths were observed, no shift was observed for the peak excitation and ir stimulation wavelengths.
