A facile fabrication of poly(methyl methacrylate)/α-NaYF4:Eu3+ tunable electrospun photoluminescent nanofibers

The photoluminescent nanofibers (PLNs) were successfully produced by incorporating α-NaYF4:Eu3+ nanophosphor into the polymethylmethacrylate (PMMA) matrix using electrospinning technique. The morphology of PLNs was investigated by scanning electron microscope (SEM) with the diameter in the range of 165–450 nm. The nanofibers revealed hypersensitivity in emission regime from orange to red (589–707 nm) with 5% concentration of nanophosphor at the excitation wavelength of 239 nm. X-ray diffraction (XRD) and photoluminescence (PL) spectroscopy confirm the uniform co-ordination (dispersion) of nanophosphor with the carbonyl group of PMMA molecular chain. The PMMA/ α-NaYF4:Eu3+ composite nanofibers have the potential application in colored light-emitting diode (LED)
