Single-crystalline oxide films of the Al 2 O 3 -Y 2 O 3 -R 2 O 3 system as optical sensors of various types of ionizing radiation: significant advantages over volume analogs

Development of Composite Scintillators Based on the LuAG: Pr Single Crystalline Films and LuAG:Sc Single Crystals

“…These results on the LY measurements of composite scintillators under α-particle excitation by 241 Am source (Figure 5a) are coherent with the LY of these samples under excitation by 239 Pu source (Table 1). Meanwhile, the variations in the content of Pb 2+ flux related impurity in LuAG:Pr SCFs grown from PbO based flux at different temperatures (Table 1) result also in the notable deviation of their scintillation LY (Figure 5a) (see also References [32,33]). Under excitation of LuAG:Pr SCF/LuAG:Ce SC composite scintillators by γ-rays from 137 Cs source, the significant Compton scattering tools are present in PHS (Figure 5b; see also Reference [27]).…”

Development of Composite Scintillators Based on Single Crystalline Films and Crystals of Ce3+-Doped (Lu,Gd)3(Al,Ga)5O12 Mixed Garnet Compounds

“…The technology of liquid phase epitaxy (LPE) offers now the possibility of developing luminescent materials based on the single crystalline film (SCF) of different oxide compounds. − The fields of application of such SCFs now include cathodoluminescent screens, , laser media, , scintillators for registration of α- and β-particles and low-energy quanta, ,, and scintillating screens for microtomography detectors using X-ray sources and synchrotron radiation. , …”
