(Scintillation Coatings on Imaging and Line Sensors)
Generally speaking phosphor coatings are used for the visualisation of energetic photons, Soft X-ray imaging, synchrotron radiation. The phosphor coating is prepared by sedimentation of phosphor grains on a solid state sensor like CCD or CMOS Sensor. Since these sensors are usually not sensitive for a wavelength < 350nm the coating acts as a spectral converter in most cases to green light. Coated solid state sensors are a much less expensive alternative to back thinned sensors if the other advantages of these sensors are not necessary for the application.
