a method of microwave annealing for enhancing the properties of organic electronic devices is provided , including the steps of providing organic electronic devices and then microwave annealing the organic electronic devices . because microwave annealing is non - contact and requires only a short time for annealing , and also because it anneals a target selectively and may anneal only the organic active layer of organic electronic device , microwave annealing allows organic molecules in the organic active layer to be rearranged quickly , so as to improve the arrangement of the organic molecules , and this in turn elevates the quantum efficiency thereof and enhances the properties of the organic electronic devices .
