文摘

All-solution-processed WQLEDs were successfully fabricated using a blue-emitting ADS329BE polymer blended with RGB QDs. Hybrid WQLEDs charge balance in the emission layer and the occurrence of FRET between the ADS329BE and the RGB QDs. The hybrid WQLEDs exhibit luminance values greater than 10,000 cd/m2 with a driving voltage in the range of 6.0-7.0 V. By doping the ADS329BE polymer in the EML, near-white light with appropriate CIE chromaticity coordinates was achieved.
