Study on cadmium sulphide nanoparticles on blue and green light emitting polymers

摘要

We demonstrate the working of organic-inorganic hybrid light emitting diodes using cadmium sulphide nanoparticles doped in light emitting polymers. Cadmium sulphide nanoparticles were prepared by precipitation technique and doped in active light emitting polymers. We used blue emitting polymer PFO and green emitting polymer F8BT as active polymers. The j-L-V curves of nanoparticles based devices were compared with polymer only standard devices. Our results show enhanced performance such as increased conductivity and higher luminance, when nanoparticle are incorporated into the device.
