We report the synthesis of nickel nanoparticles (NPs) by wet chemical route and its blend with emissive PDY-132(super yellow) matrix for application in Organic Light-Emitting Devices (OLEDs). Wet Chemical Synthesis allows the successful synthesis of CTAB (Cetyl Trimethyl Ammonium Bromide) capped nickel (Ni) nanoparticles having a size of 5–7 nm. The synthesized colloidal having nanoparticles can be easily mixed with emissive polymer solutions to obtain a blend for OLED application. From the experimental results, it is observed that turn on voltage decreases to 3.54V from 9V and current increases to 14mA from 4mA after adding Ni NPs into the emissive layer. The narrowing and sharpening of electroluminescence were observed.
