What is the difference between phosphor and YAG scintillators?

Phosphor generates more photons (light signal) than YAG, but the photon generation is more uniform (less noise) for YAG than phosphor. Phosphor is typically offered for applications that require more sensitivity (such as low dose on beam sensitive specimens). YAG is typically offered for photographic image quality. Please note that YAG is not available for TEM voltages above 200kV.
