Electroluminescent organic light emitting micro/nanofibers fabricated using three-fluid coaxial electrospinning

This paper presents the development of three-fluid coaxial electrospinning technology and its application in electroluminescent organic light emitting micro/nanofibers (OLEFs). It is demonstrated that one-dimensional micro/nano-scale light sources can be realized using a single-step, substrate-free fabrication process - three-fluid coaxial electrospinning. The OLEF devices are formed in air rather than on a substrate before coming to the object surface of interest, and do not require any thin-film deposition and high-resolution lithography processes that are generally used in current light emitting device technologies. Such micro/nano-scale OLEFs could be beneficial in applications ranging from bio-imaging to chemical and biological sensing to other nano-scale luminescence in general.
