Abstract:
High-quality non-stoichiometric NiO x  nanoparticles are synthesized by a facile chemical precipitation method. The NiO x  film can function as an effective p-type semiconductor or hole transport layer (HTL) without any post-treatments, while offering wide temperature applicability from room-temperature to 150° C. For demonstrating the potential applications, high efficiency is achieved in organic solar cells using NiO x  HTL. Better performance in NiO x  based organic light emitting diodes is obtained as compared to devices using PEDOT:PSS. The solution-processed NiO x  semiconductors at room temperature can favor a wide-range of applications of large-area and flexible optoelectronics.

Claim (Index 5):
A method for preparing non-stoichiometric NiO x  nanoparticles, with a composition of NiO (Ni 2+ ), NiOOH (Ni 3+ ), and Ni 2 O 3  (Ni 3+ ), wherein the method comprises the steps of:\n using a base to react with Ni ions in water without added heat to form an electrically insulated and undispersed intermediate; grinding the intermediate to form it into a uniform grain size; and combusting the intermediate in air at a temperature of 270\u00b0 C. or less to cause oxygen to interact with a nickel-deficient lattice and further form non-stoichiometric NiO x  nanoparticles; wherein the step of using a base to form an electrically insulated and undispersed intermediate involves using a dispersing agent that is water/methanol, water/ethanol, or water/other alcoholic solvents.
