Researchers create full-color fiber light-emitting diodes based on perovskite quantum wires
Researchers from the Hong Kong University of Science and Technology, Sun Yat-sen University and Nanjing University of Science and Technology have uniformly grown all-inorganic perovskite quantum wire arrays by filling high-density alumina nanopores on the surface of Al fibers with a dip-coating process.
Fiber light-emitting diodes (Fi-LEDs), which can be used for wearable lighting and display devices, could be a key component for fiber/textile electronics. However, as a number of challenges exist with this technology, researchers are trying to address issues like on device fabrication with fiber-like substrates, as well as on device encapsulation.
