Application of scintillators based on single-crystalline Lu₃Al₅O₁₂:Ce³⁺ films for radiation monitoring in biology and medicine

Possibility of producing screens of X-ray detectors using liquid phase epitaxy on Y₃Al₅O₁₂ substrates covered by Lu₃Al₅O₁₂:Ce single crystalline films (SCF) is studied. Optical, luminescent and luminous characteristics of these SCF doped with isoelectronic La, Y, Sc impurities are analyzed. The poss...
