Abstract: The spectra of write, read and output in SrS(Eu, Sm) were reported. The linearity of outputing-stimulated luminescence intensity versus writing-light intensity and reading light- in-tensity were given. The function of image storage and image addition and subtraction were exper-imentally demonstrated, using SrS(Eu, Sm) film whose thickness is approximately-100μm. The results show that this material has very greatly potentiality for application in optical information storege and processing.

Key words: infrared stimulated luminescence, electron-trapping image storage, image addition, image subtraction
