Self-Assembly of Perovskite Crystals Anchored Al O -La O Nanofibrous Membranes with Robust Flexibility and Luminescence.

Inorganic luminescent materials as one of the important high-performance materials are widely used for industry and scientific research, mainly owing to their outstanding luminescence properties. However, inorganic luminescent materials are typically brittle and inelastic, which greatly limit their use in practical applications, particularly in flexible optoelectronic devices. In this work, it is shown that "plum-pudding" like CsPbBr /Cs PbBr perovskite crystals anchor onto Al O -La O (CCAL) nanofibrous membranes, which are synthesized via a facile electrospinning and subsequent supersaturated recrystallization process.

Facile synthesis of luminescent and amorphous La₂O₃-ZrO₂:Eu³⁺ nanofibrous membranes with robust softness.

Novel luminescent and amorphous La2O3-ZrO2:Eu(3+) (LZE) nanofibrous membranes with robust softness are fabricated for the first time via a facile electrospinning technique. By incorporating zirconium oxide, the as-prepared lanthanum oxide nanofibrous membranes can be dramatically changed from extreme fragility to robust softness. Meanwhile, the softness and luminescent performance of LZE nanofibrous membranes can be finely controlled by regulating the doping concentration of zirconium oxide and europium in lanthanum oxide nanofibers.

Fabrication and durable antibacterial properties of electrospun chitosan nanofibers with silver nanoparticles.

Non-precipitation chitosan/silver nanoparticles (AgNPs) in 1% acetic acid aqueous solution was prepared from chitosan colloidal gel with various contents of silver nitrate via electron beam irradiation (EBI). Electrospun chitosan-based nanofibers decorated with AgNPs were successfully performed by blending poly(vinyl alcohol). The morphology of as-prepared nanofibers and the size of AgNPs in the nanofibers were investigated by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM).
