All Optical Fiber Sensor based onOptically Stimulated Luminescencefor radiation detection

The OSL phenomenon offers the same advantages as TLD and the interesting possibility of a remote optical stimulation. On this assumption, we have developed a radiation sensor based on an Optically Stirnulable Luminescent (OSL) material [2,3] coupled with an optical fiber. Rare earth doped Alkaline Earth Sulfides (ARS) were selected as phosphor materials due to their relatively low Zeff (14.5 for Magnesium sulfide).
