摘要：

LaNi5 alloy films have been prepared by magnetron sputtering and annealed in air. The structure, surface morphology and elements composition of the films before and after annealing were analyzed by X-ray diffraction, atomic force microscopy and X-ray photoelectron spectroscopy, respectively. The results showed that specific surface area of LaNi5 films was increased and a kind of surface structure of La2O3-Ni was formed after annealing. The hydrogen sensitivity of the annealed samples was studied. The results indicated they are in response to hydrogen at room temperature in air without activation in hydrogen atmosphere, which suggested LaNi5 alloy films have large potential application in hydrogen sensor. ©.
