“…Furthermore, advanced composite scintillators [ 1 , 9 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ] and thermoluminescent (TL) detectors [ 23 , 24 , 25 , 26 ] of “phoswich-type” (phosphor sandwich) may be fabricated by the LPE method for simultaneous registration of different components of ionizing radiation, namely, for content analysis of the mixed radiation fluxes involving ionizing particles with various penetration depths. These composite scintillators and detectors comprise epitaxial crystalline structures, including one/two SCFs for registration of low-penetrating α- and β-particles, and bulk single crystal (SC) substrates for registration of the high-penetrating radiation (X- or γ-rays) ( Figure 1 ).…”
