In this work we report the recent results of our investigation on visible emission properties of the polymer nanocomposites doped with oxide and fluoride nanopowders activated with praseodymium ions. The set of LaAlO3 and YF3 nanopowders differing in active ions concentration, was carefully characterized with respect of their structural and luminescent properties. Also the PMMA-based nanocomposites doped with these nanopowders were manufactured and characterized. The measurements of excitation and emission spectra as well as fluorescence decays enabled comparison of emission properties of nano-composites and original nanopowders and discussion of the main excitation and deexcitation mechanisms, responsible for the optical properties of developed materials. This, in turn will enable optimization of developed manufacturing technology.
