Luminescent Polyacrylonitrile(PAN) Electrospinning Nanofibers Encapsulating Silica nanoparticles carried Ternary Europium Complex

A novel luminescent Polyacrylonitrile(PAN) nanofibre encapsulating silica nanoparticles carried ternary europium complex with α-thenoyltrifluoroacetone(htta) and 1,10-phenanthroline (phen) [Eu(tta)3phen (EuTP)] was obtained via electrospinning technique. Silica nanospheres carried Eu3+ complex achieved by sol-gel technique. The structural investigations by TEM and XRD indicated that europium complex behaves nanocrystals with diameter of ~20 nm that are embedded onto an amorphous nanoSiO2 (~500 nm) surface. Luminescent spectra and fluorescent optical microscopic photograph of electrospinning fibers showed that introducing the europium complex in nanoSiO2 can improve the luminescence properties and increase the compatibility between the pure complex and silica. Therefore, this kind of organic-inorganic hybrid materials could be a candidate applied to excellent optical devices.
