Luminescent properties of dysprosium(III) ions in LaAlO3 nanocrystallitesK.Lemański,P.J.DereńInstitute of Low Temperature and Structure Research,Polish Academy of Sciences摘 要:The absorption and emission spectra as well as decay time profile of Dy3+ ions in LaAlO3 nanocrystals were analyzed.The crystal structure of LaAlO3 was confirmed from XRD......
STRUCTURAL REARRANGEMENT AND PROPERTIES OF QUENCHED TITANATE GLASSES REHEATED AT T_g陈奇摘 要:<正>The structural rearrangement of quenchedtitanate glasses reheated at Tg. was investigated by ESR andIR spectroscopies. From the ESR observations it is suggestedthat the structure was readjtsted and became more compactafer the heat-treatment. A removal......
