Abstract
We present studies on bioactive silica-based glass nanoparticles showing photoluminescence. The sol–gel or solvothermal route was used for syntheses. Lanthanides, zinc oxide or phthalocyanine complexes ensured light emission. The structural, morphological, and optical properties were examined. During the bioactivity tests, when particles were immersed in SBF, ions release to the medium and hydroxyapatite formation were analyzed. Composites with graphite oxide were described as well. The systems are promissing for monitoring structural changes of the glass immersed in biological fluids, bioimaging or photodynamic therapy. Research was performed within Polish–Ukrainian Joint Exchange Project and NSC grants 2016/23/B/ST5/024830, 2016/22/E/ST5/00530.
