Ionic transition-metal complex (iTMCs)-based electro-luminescent nanofibers (TELFs) are developed by using coelectrospinning. A single TELF consists of a Galistan liquid metal core (cathode), an iTMC-based polymer shell, and ITO thin film coating (anode). Lights emitted from the TELFs can be detected CCD camera at 4.2 V seen naked eyes 5.6 in nitrogen. The structurally self-supporting but do not require physical substrate (generally relatively bulky heavy) to support them, rendering one-dimensional light sources more flexible, lightweight, conformable. This technology beneficial many research development areas such as optoelectronic textile, bioimaging, chemical biological sensing, high-resolution microscopy, flexible panel displays, particularly iTMCs with emission different wavelengths available.
