In this work we summarize the results of our research on design and development of the PMMA-based composites doped with lanthanum aluminum oxide (LaAlO3) nanocrystals activated with selected rare-earth ions - dysprosium, holmium, thulium and praseodymium. A set of rare-earth doped nanopowders, differing in activators' concentration was manufactured and carefully characterized with respect of luminescent properties in the visible spectral range. The samples of optimal luminescent features were introduced into PMMA polymer, constituting the luminescent composite materials with the active centers shielded from the parasitic interactions with polymer phonons. These, in turn, were subjected to optical characterization covering luminescence spectra and kinetics measurements, which enabled comparison of the luminescent features and assessment of the quality of developed materials as well as correctness of proposed approach.
