He was instrumental in the development of the YAlO 3:Ce technology for low energy gamma-rays detection. An important achievement has been the discovery of Pr 3+ doped scintillation media and GdAlO 3:Ce and LuAlO 3:Ce scintillation materials. His study promoted the understanding of scintillation mechanism in many crystals.
