Intrinsically Fluorescent Microspheres with Superior Thermal Stability and Broad Ultraviolet-Visible Absorption Based on Hybrid Polyphosphazene Material

More and more attention is focused on monodispersed, functionalized microspheres with tunable size. In this article, a facile, efficient self-assembly process is successfully developed to fabricate novel monodispersed microspheres based on hybrid polyphosphazene, and the size of the microspheres is proven to be easily tailorable. The polymer exhibits excellent thermal and intrinsically fluorescent properties which make up the deficiency of generally fluorescent material prepared by embedding with quantum dots or dyes in some special domains. In addition, a broad ultraviolet-visible absorption is observed from 300 to 450 nm, and all these superior properties may result in potential applications in ablation-resistant materials, solar energy photoelectric materials and biomaterials.
