Fabrication of CdSe quantum dots-PHF organic hybrid light emitting diodes

Abstract

Quantum dots (QDs) have been attracted an active interest for light emitting device due to their unique high luminescence efficiency and narrow emission spectra as a result of the strong electrons confinement in its nanoscale core that is potential for production of pure colour light emission. In this work, a CdSe quantum dot-PHF organic hybrid light emitting devices have been fabricated. To study the effect of the CdSe QDs layer in the performance of the devices, variations of QDs layer were prepared. It is found that the present of the QDs layer improved the electroluminescence property of the device. In this article, we report the fabrication of light emitting diode using quantum dots that hybridize with PHF organic material. The light emitting device was found to give a bright green colour emission centering at 533.61 nm. The effect of QDs layer on the performance of light emitting devices was discussed.
