Abstract
A method of forming a n-doped semiconductor layer wherein a film comprising an organic semiconductor and an n-dopant reagent is irradiated by light having a wavelength that is within an absorption range of the organic semiconductor, and wherein an absorption maximum wavelength of the n-dopant precursor is shorter than any peak wavelength of the light. The n-doped semiconductor layer may be an electron-injection layer of an organic light-emitting device.
