| Abstract: | Luminescent properties of Y2O3 and LaAlO3 nanopowders doped with Pr3+ ions and PMMA-based composite materials doped with these powders were reported.The set of active nanopowders differing in praseodymium ions concentration was prepared using sol-gel method and carefully characterized with respect to emission properties in the visible spectral range.In particular,the excitation and emission spectra were measured together with fluorescence decay profiles and the differences between optical properties of thes... |
