| description | This work is dedicated to the development of new types of composite thermoluminescent (TL) detectors for simultaneous registration of the different components of ionization radiation based on the single crystalline films (SCFs) of Ce<sup>3+</sup>-doped Lu<sub>3−x</sub>Gd<sub>x</sub>Al<sub>5</sub>O<sub>12</sub>:Ce (x = 0−1.5) garnet and Y<sub>3</sub>Al<sub>5</sub>O<sub>12</sub>:Ce (YAG:Ce) substrates using the liquid phase epitaxy (LPE) growth method. For this purpose, the TL properties of the mentioned epitaxial structures were examined in Risø TL/OSL-DA-20 reader under excitation by α- and β-particles from <sup>242</sup>Am and <sup>90</sup>Sr-<sup>90</sup>Y sources. We have shown that the cation engineering of SCF content can result in more significant separation of the TL glow curves of SCFs and substrates under α- and β-particle excitations in comparison with the prototype of such composite detectors based on the Lu<sub>3</sub>Al<sub>5</sub>O<sub>12</sub>:Ce (LuAG:Ce)/YAG:Ce epitaxial structure. Specifically, the difference between the TL glow curves of Lu<sub>1.5</sub>Gd<sub>1.5</sub>Al<sub>5</sub>O<sub>12</sub>:Ce SCFs and YAG:Ce substrates increases up to 120 K in comparison with a respective value of 80 degrees in the prototype based on the LuAG:Ce/YAG:Ce epitaxial structure. Therefore, the LPE-grown epitaxial structures containing Lu<sub>1.5</sub>Gd<sub>1.5</sub>Al<sub>5</sub>O<sub>12</sub>:Ce SCFs and Ce<sup>3+</sup>-doped YAG:Ce substrate can be successfully applied for simultaneous registration of α- and β-particles in mixed fluxes of ionization radiation. |
