Bioactive glasses are materials which can be used in medicine for regeneration of hard and soft tissues. Their functionalization with active molecules or addition to composites broaden significantly the possible range of glass applications. Hereby, we describe photoactive nanoparticles of CaO-SiO-PO glass modified with dichlorohafnium (IV) phthalocyanine. The low-temperature, sol-gel based reverse micelle method was proposed for the synthesis, which allowed introduction of metal organic molecules into the glass composition. The morphology, structure, and composition of the material was described showing that spherical but agglomerated glass nanoparticles (size below 100 nm) were obtained in the ternary system. It was also shown that optical properties of the phthalocyanine complex were maintained after immobilization of the dye in the glass. The photoluminescence and generation of singlet oxygen molecules were observed under the light irradiation of the glass.
生物活性玻璃是可用于医学中硬组织和软组织再生的材料。它们与活性分子的功能化或添加到复合材料中显著拓宽了玻璃应用的可能范围。在此，我们描述了用二氯铪（IV）酞菁修饰的CaO-SiO-PO玻璃的光活性纳米粒子。提出了基于低温溶胶-凝胶的反胶束法进行合成，该方法允许将金属有机分子引入玻璃组成中。描述了材料的形态、结构和组成，表明在三元体系中获得了球形但团聚的玻璃纳米粒子（尺寸低于100nm）。还表明，将染料固定在玻璃中后，酞菁配合物的光学性质得以保持。在玻璃的光照下观察到了光致发光和单线态氧分子的产生。
