Abstract: 
TiO2 has been recently used in organic light emitting devices (OLED) in different layers as embedded nano particles, nano composites. These nano materials are reported to be useful in enhancing OLED device performance such as charge injection. Usually, TiO2 is industrially synthesized by either sulfate or chloride processes, which are known to be environmentally hazardous methods. Here we are comparing TiO2 synthesized by a closed processes under low temperature against commercial TiO2 to be used in OLED applications by preparing submerged TiO2 nanoparticles in 2, Poly(9-vinylcarbazole (PVK) by spin coating and vacuum depositing organic semiconductor diodes and later trying to evaluate charge transport characteristics.
