Abstract
The work is dedicated to investigation of the luminescent properties of UV-emitting single crystalline films (SCF) based on the Lu3Al5O12:La and Lu3Al5O12:Pr garnet and LuAlO3:Ce perovskite compounds grown by liquid phase epitaxy method from the PbO-B2O3 flux onto Y3Al5O12 and YAlO3 substrates, respectively, for testing as scintillation screens in high-resolution microimaging detectors used in applications with synchrotrons radiation. The first image with a spatial resolution of about 1.5 μm of X-ray excited resolution target was obtained using only the UV part of the light of the LuAG:La SCF scintillators. The possible ways for improvement of figure-of-merit of UV emitting SCF scintillators and increase of spatial resolution of the detector are discussed.
