摘要：

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 8-22V. This kind of new ECP film afforded more opportunities to develop color-stable white-light-emission.
