Scintillators are indispensable for a number of technologies, including x-ray detectors used in medical imaging and nondestructive inspection, phosphor screens in night-vision systems, electron detectors in electron microscopes, and electromagnetic calorimeter in high-energy physics experiments. Polycrystalline scintillator films are used for most of these applications, especially in x-ray flat panel detector (FPD). Research in this field is largely driven by the aim of high spatial resolution and low afterglow, for tiny-spot identification and high-speed imaging. In terms of spatial resolution, in addition to high scintillation yield, scintillators with optical wave-guiding effect have been designed. The columnar structured scintillator films enjoy low scattering and inter-pixel cross-talk and have demonstrated their intrinsic advantages in high-resolution and high-pixel fill factor for x-ray FPD.
