The project aims to study the possibility of development of ultra-fast (10 ps) scintillation detectors for positron emission tomography, which can significantly improve the quality of medical care and the accuracy of experiments in high-energy physics. The functional properties of scintillation detectors based on metamaterials obtained on the basis of a crystalline substrate (BGO type) with a layer of composite containing fast luminescent nanoparticles (perovskite-type, Ga2O3) will be studied. To achieve this goal one needs to obtain bulk crystal substrates and nanoparticles of fast luminescent materials, to incorporate synthesized nanoparticles into protective composite filler on the substrate surface, and to study the functional properties of such metamaterials. Research methods include measurements of optical-luminescent properties, luminescence decay time and structural characteristics. To determine the stability of the properties of developed metamaterials-based detectors, the interaction of nanoparticles with composite filler (varnishes, polysiloxanes, etc.) and substrate material should be studied and time change of the functional parameters of the detectors should be determined.
