The work is dedicated to the development of new types of UV-emitting scintillators based on single crystalline films (SCF) of aluminum perovskites and garnets grown by the liquid phase epitaxy method. The peculiarities of growth and properties of the following three types of UV SCF scintillators are considered in this work: i) Ce-doped SCF of Y-Lu-Al-perovskites with the Ce3+ emission in the 360-370 nm range of the decay time of 16-17 ns; ii) Pr-doped SCF of Y-Lu-Al garnets with the Pr3+ emission in the 300-400 nm range of the decay time of 13-17 ns; iii) La3+ or Sc3+ doped SCF of Y-Lu-Al-garnets, emitting in the 290-400 nm range due to formation of the LaY,Lu, ScY,Lu and ScA1 centers with decay time of the order of hundreds of nanoseconds. Preliminary test of these SCFs scintillators for visualization of X-ray images at European Synchrotrons Radiation Facility are presented as well.
