Position:

senior scientist in Laboratory of Luminiscence and Scintillation Materials, Department of Optical Materials

Field of interests

• scintillation properties of rare earth ions (mainly Ce3⁺ and Pr³⁺) in inorganic crystals, especially in oxide crystals (Lu-Y pure and mixed garnets, perovskites and silicates). Research of (Lu-Y)-garnet and perovskites thin epitaxial layers grown by LPE metod,
• mechanisms of scintillation processes and their efficiency in garnets, perovskites and silicates but also other crystals are studies as e.g. PbWO₄ (PWO),
• development of measuring methods for scintillation research, especially use of hybrid photomultipliers (HPMT) – properties as photoelectron or light yields, energy resolution, proportionality and time dependence are studies
• cooperation with CERN, Geneva, Switzerland in (i) PHOS detector of ALICE LHC experiment (PHOS consists of PWO crystals) and (ii) investigation of various scintillators using HPMT set-up (developed for characterisation of fast and heavy PWOs for LHC calorimeters) in PH-DT2 group
