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

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...

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 possibility of crystallization of Lu₃Al₅O₁₂: Ce SCF on Y₃Al₅O₁₂ substrates by means of matching the lattice parameters of these garnets, when Lu³⁺ ions in Al³⁺ octa-sites, is proved. With the aim of matching the emission spectra of SCF based on Lu₃Al₅O₁₂: Ce, with the spectral sensitivity range of radiation detectors – CCD cameras – we investigated SCF containing Gd³⁺, Tb³⁺, and Eu³⁺ impurities. The maximum light yield, exceeding that of analogs based on Y₃Al₅O₁₂:Ce SCF by the factor of 1.1-1.5, is shown to be intrinsic for Lu₃Al₅O₁₂:Ce³⁺, Lu₃Al₅O₁₂:Ce, Y, La and Lu₃Al₅O₁₂:Ce, Tb SCF. An increase of the effective atomic number Zeff and density r up to the values of 60.6 and 7.35 g/cm³ respectively, enables the efficiency of X-ray absorption in comparison with Y₃Al₅O₁₂:Ce³⁺ SCF by the factor of 2.5–8 higher and to reach spatial resolution not less than 0.75–1.0 µm at the SCF thickness of 1.0–2.0 mm.
The work has been fulfilled under financial support of INTAS-Ukraine (project No 95/01666).
