Flexible Light Emitting Devices Based on Chirality-sorted Semiconducting Carbon Nanotube Films

Near-infrared light emitting devices based on chirality-sorted (8,3), (8,4) enriched carbon nanotubes (CNTs) are fabricated on transparent and flexible substrate. The devices emit near infrared light with well-defined wavelength, narrow peak width and high intensity. 500 times bending test also shows that the electric properties and electroluminescence (EL) spectra of devices do not decay apparently. This work demonstrates that chirality-sorted CNTs have large advantages in transparent and flexible infrared light source applications.
