Description
The report presents our achievement in the developments of all-solid state hybrid scintillators based on single crystalline films (SCF) and single crystals (SC) of mixed garnet compounds for registration of different types of particles and quanta in the mixed fluxes of ionizing radiations. Hybrid scintillators have been made in the form epitaxial structures containing one or two scintillators in the form of SCFs grown by liquid-phase epitaxy (LPE) method onto substrates from SC scintillators. Film and crystal parts of hybrid scintillators were fabricated from effective scintillation materials with garnet structure with significantly different luminescent spectra or scintillation decay kinetics on the basis of different combinations of SCs and SCFs of the Ce3+, Pr3+ and Sc3+ doped Lu3Al5O12 garnets as well as the SC of Ga3Ga2.5Al2.5O12:Ce garnet and SCFs of (Lu,Gd)3(Al,Ga)5O12:Ce and (Tb,Gd)3(Al,Ga)5O12:Ce mixed garnets.
The report presents the original results on fabrication of scintillators based on the materials under study in the form of SC, SCF and hybrid scintillators as well as the results of investigation of their luminescent and scintillation characteristics. We provide also the comprehensive analyzes of the luminescent and scintillation properties of Ce3+, Pr3+, Sc3+ doped Lu3Al5O12 garnets, prepared in the SCF form in comparison with their bulk SC counterparts.
The results of testing the developed hybrid scintillators in the detectors for radiation monitoring of different components of mixed ionizing fluxes (α-particles and γ–quanta) will be presented as well.
