The lithium-doped nickel oxide (L-NiO) films were synthetized using the modified spray pyrolysis method with a two-step grown process. By observing the spectra of X-ray photoemission spectroscopy of L-NiO films, the intensity of Ni 2p3/2 peak of Ni3+ bonding state increases with increasing Li concentration that causes the decrease of transparency and resistivity. The L-NiO films with optimum characteristics were obtained at Li = 8 at%, where a p-type resistivity of 4.1 × 10-1 Ω cm and optical transparency above 76% in the visible region are achieved.
采用改进的两步喷涂热解法合成掺锂氧化镍（L-NiO）薄膜。通过观察 L-NiO 薄膜的 X 射线光电子能谱光谱，Ni3+键合态的 Ni 2p3/2 峰强度随 Li 浓度的增加而增加，导致薄膜的透明度和电阻率降低。当 Li 浓度为 8 at%时，L-NiO 薄膜具有最佳特性，此时薄膜的电阻率为 4.1×10-1 Ω·cm，可见光区的光学透明度超过 76%。
