The BAS-MS, like all Imaging Plates, has a flexible polyester base coated with highly dispersed barium fluorohalide phosphor crystals (BaF(Br,I):Eu2+).
When a radioactively labeled sample is exposed to an IP, the energy from that sample is transferred to the phosphor crystals, and stored as trapped electrons. In short, the electrons become trapped to form 'F-centers' in the BaF(Br,I) matrix.
Scanning the exposed IP with a He-Ne laser (633nm) releases the trapped electrons and photons at about 400nm. This process is known as photo-stimulated luminescence. The blue light emitted is collected to produce the digitized image.
