title: Novel composite layer based on electrospun polymer nanofibers for efficient light scattering.
abstract: We fabricated a PAN (polyacrylonitrile) NF (nanofiber)-embedded composite layer to adjust the light-control layer in light-emitting-diode (LED) and organic-light-emitting-diode (OLED) lighting systems with unique optical characteristics, for effective light scattering. The newly designed light-control composite layers with a composition of PAN NF/SU-8 exhibited a change in the optical properties, which was identified by the diameter control of the NF using a simple process. The change in the optical properties was largely dependent on the embedded NF's features. Therefore, the NF can be applied in different types of lighting systems, depending on each lighting device's purpose.
