Abstract

Graphical abstract: Emission spectra in a wide range (300–750 nm) of the LEC composite electrodes with 40% of luminophors: fluoride doped with the Tb 3+, Sm 3+ or Dy 3+ ions and vanadate doped with the Sm 3+ or Dy 3+ ions. Abstract: The research is focused on hybrid, bifunctional composite materials, in terms of their application to innovative lightning systems. The main target was to obtain emissions in such materials for various colours other than red. In addition, the doping concentration was optimized and mechanical properties of the tested materials were improved. The materials were characterized by X-ray diffraction analysis and scanning (SEM) and transmission (TEM) electron microscopy. The spectroscopic properties were investigated and additional calculations of the spectroscopic data were also performed.
