Transparent optical ceramic coating materials have been fabricated from europium-doped lutetium oxide (Lu2O3:Eu) using physical vapor deposition and chemical vapor deposition techniques. The non-pixilated film coatings have columnar microcrystalline structure and excellent properties for use as radiological scintillators, namely very high density, high effective atomic number, and light output and emission wavelength suitable for use with silicon-based detectors having a very high quantum efficiency. The materials can be used in a multitude of high speed and high resolution imaging applications, including x-ray imaging in medicine.
