In spite of strong inter-shell 4f ® 5d absorption bands at ambient pressure the cerium luminescence in Gd3Ga5O12 is entirely quenched even at low temperature. It has been shown that applying pressure allows for recovering the 5d ® 4f radiative transitions. Further increase of pressure improves the emission efficiency. This effect is analyzed in terms of two possible phenomena: (i) by pressure-induced electronic crossover of the excited 5d energy level of the Ce3+ with the conduction band bottom of host crystal, and (ii) by decrease of electron-lattice coupling with increasing pressure, resulting in reducing of Stokes shift and non-radiative transitions between the low vibrational levels of the 5d state and high vibrational levels of the ground 4f state.Item Crystal and twin structure of LSGMn-05 anode material for SOFC(Видавництво Львівської політехніки, 2012) Tataryn, T.; Vasylechko, L.; Savytskii, D.; Berkowski, M.; Paulmann, C.; Bismayer, U.The structure of perovskite-type La0.95Sr0.05Ga0.95Mn0.05O3-x crystals has been investigated using high-resolution X-ray powder diffraction technique in the temperature range of 298–1173 К. A phase transition from orthorhombic (Pbnm) to rhombohedral (R 3 c) has been detected near 340 К. A chevron-like configuration of ferroelastic domain structure was observed in rhombohedral La0.95Sr0.05Ga0.95Mn0.05O3-x crystal using the Laue technique. The chevron-like pattern is formed by the intersection of Wtype domain walls (211), (101) and (110).Item Optical studies and spectroscopic peculiarities of dysprosium doped Gd2SiO5 single crystals(Видавництво національного університету „Львівська політехніка”, 2009) Lisiecki, R.; Solarz, P.; Dominiak-Dzik, G.; Ryba-Romanowski, W.; Berkowski, M.; Głowacki, M.Item Crystal growth and structure characterization of rare earth double tungstate(Видавництво національного університету „Львівська політехніка”, 2009) Iwanowski, P.; Domukhovski, V.; Berkowski, M.
