| Popis: | This work reports on the implementation of electrospinning ({ES}) as a facile route to encapsulate nano engineered materials in a polystyrene ({PS}) matrix. We applied {ES} to co encapsulate two kinds of nanoparticles i.e. upconversion nanophosphors ({UCNPs}) and superparamagnetic iron oxide nanoparticles ({SPIONs}) in polystyrene ({PS}) based micro and nano fibers ({PSFs}). This approach made it possible to integrate near infrared ({NIR}) light sensitive 500 nm ß {NaYF}4:Yb Er {UCNPs} with 10 nm ? Fe2O3 {SPIONs} in {PS} fibers. During the {ES} process {PSFs} were additionally loaded with a well established singlet oxygen (1?g) photosensitizer rose bengal ({RB}). The thus obtained {PSFs} revealed the promising features of prospective multi functional magnetic photoluminescent photocatalytic nano constructs. |
