“…Existence of differences in thermoluminescent properties of LSO SC and SCF counterparts was reported in our previous work [11]. We showed that thermoluminescence glow curves strongly depend on crystalline form of the SC and SCF samples.…”

In this work the comparative analysis of thermoluminescent properties of undoped and Ce-doped single crystals (SC) and single crystalline films (SCF) of (LSO) and (YSO) orthosilicates were performed. The SC samples were prepared with the Czochralski method, and SCF were grown by the liquid phase epitaxy technique. We show that such different methods of material preparation resulted in different thermoluminescent properties of undoped and doped LSO and YSO SC and SCF caused by the presence host defects (first of all, oxygen vacancies) as trapping centers in SC and formation of pair centers in SCF.

“…The most common TL detectors are those based on lithium fluoride [ 32 , 33 ], but new materials and new applications are still under development [ 34 ]. In the past, some types of thin-film TL detectors for measurements of weakly penetrating radiation [ 35 , 36 , 37 , 38 , 39 ] have been developed. Recently, we have also studied the possibility of using LPE-grown SCFs of oxide compounds (perovskites, garnets, orthosilicates) for this purpose [ 23 , 24 , 25 , 26 , 39 ].…”

This manuscript summarizes recent results on the development of composite luminescent materials based on the single-crystalline films and single crystals of simple and mixed garnet compounds obtained by the liquid-phase epitaxy growth method. Such composite materials can be applied as scintillating and thermoluminescent (TL) detectors for radiation monitoring of mixed ionization fluxes, as well as scintillation screens in the microimaging techniques. The film and crystal parts of composite detectors were fabricated from efficient scintillation/TL materials based on Ce3+-, Pr3+-, and Sc3+-doped Lu3Al5O12 garnets, as well as Ce3+-doped Gd3−xAxAl5−yGayO12 mixed garnets, where A = Lu or Tb; x = 0–1; y = 2–3 with significantly different scintillation decay or positions of the main peaks in their TL glow curves. This work also summarizes the results of optical study of films, crystals, and epitaxial structures of these garnet compounds using absorption, cathodoluminescence, and photoluminescence. The scintillation and TL properties of the developed materials under α- and β-particles and γ-quanta excitations were studied as well. The most efficient variants of the composite scintillation and TL detectors for monitoring of composition of mixed beams of ionizing radiation were selected based on the results of this complex study.

“…In our previous works [11][12][13], we also studied the thermoluminescence (TL) properties of Ce 3+ -doped LSO and YSO SCFs grown by the LPE method from PbO-B 2 O 3 flux. We have shown that the LSO:Ce and YSO:Ce SCFs exhibit unexpected strong thermoluminescent signal above room temperature (RT) [11][12][13]. Such promising results led us to further research in this subject.…”

“…In our last works [11][12][13], we assumed that the formation of such trapping centers in LSO:Ce and YSO:Ce SCFs is related to the use of PbO-based flux and Pt mounting for the crystallization of these films. The nature of these traps is mainly caused by the presence of Pb 2+ (from flux) and Pt 4+ (from crucible) contaminations in these SCF samples and the formation of different local charge and volume compensated lattice defects, such as the oxygen or cation vacancies around the mentioned impurities, which can act as trapping centers in the TL of these SCFs [11][12][13].…”

In this work we show the influence of material preparation technology on the thermoluminescent properties of single crystalline films (SCFs) of Ce 3+ -doped Lu 2 SiO 5 (LSO) and Y 2 SiO 5 (YSO) orthosilicates. LSO:Ce and YSO:Ce SCFs were grown by the liquid phase epitaxy method from two different melt-solutions based on PbO-B 2 O 3 and Bi 2 O 3 fluxes. Absorption, cathodoluminescence, and thermoluminescent properties of LSO:Ce and YSO:Ce SCFs grown from the two previously mentioned types of fluxes were compared, and results of spectrally resolved thermoluminescence measurements and thermoluminescent glow curves of SCFs recorded in different spectral ranges were presented. We have found that the observed differences in thermoluminescent properties of the SCFs under study can be caused by the
