Color-stable White Electroluminescence Based on a Cross-linked Network Film Prepared by Electrochemical Copolymerization

The first white‐emissive cross‐linked films and devices obtained by electrochemical copolymerization that have significantly improved color stability are reported (see figure). The device exhibited the CIE coordinates of (0.33, 0.35), a CRI of 88, and extremely stable white‐light emission over a wid...

Description
Summary:The first white‐emissive cross‐linked films and devices obtained by electrochemical copolymerization that have significantly improved color stability are reported (see figure). The device exhibited the CIE coordinates of (0.33, 0.35), a CRI of 88, and extremely stable white‐light emission over a wide range of driving voltages of 8–22 V. This kind of new ECP film afforded more opportunities to develop color‐stable white‐light‐emission.
