Electroluminescent Characteristics of DBPPV-ZnO Nanocomposite Polymer Light Emitting Devices.

We have demonstrated that fabrication and characterization of nanocomposite polymer light emitting devices with metal Zinc Oxide (ZnO) nanoparticles and 2,3-dibutoxy-1,4-poly(phenylenevinylene) (DBPPV). The current and luminance characteristics of devices with ZnO nanoparticles are much better than those of device with pure DBPPV. Optimized maximum luminance efficiencies of DBPPV-ZnO (3:1 wt%) before annealing (1.
