Description: Organic electroluminescent devices are currently attracting a lot of attention because they possess many features that are suitable for display applications. In order to make these devices more commercially available, one of the challenges involves lowering the operating voltage and increasing the power efficiency in them, so as to increase their lifetime. As most organic materials have mobility of holes twice that of electrons, these devices suffer from an imbalanced injection of carriers to recombine. In this work,  n-type doping of the electron transport layer (ETL) has been carried out in both Alq and fullerene (C60 or C60/C70). Specifically, studies were carried out on pure Alq, LiF-doped Alq, pure fullerene, Alq-doped C60/C70, LiF-doped C60/C 70, and Ag-doped C60/C70. Fine-tuning in terms of their respective deposition rates and thickness for the co-evaporated materials prove critical in optimizing the device performance.
