Paper Abstract

Li2B4O7 thin films were fabricated by screen-painting method on graphite substrates, and annealed at 300°C, 500°C, 600°C and 800°C for 3 hours, respectively. X-ray diffraction analyses show that the crystallinity of the films depends on the annealing temperature. The X-ray diffraction reflections of films become stronger after annealed at 300°C while a strong peak of graphite substrate appears. The XRD reflections of Li2B4O7 layers broaden and weaken when annealed at 500°C-600°C.When the sample was annealed at 800°C, the XRD peaks of films become sharper and stronger again. These results indicate that the optimum annealing temperature for Li2B4O7 thin films is 300°C or above 600°C. The SEM observations shows that the grain size is larger after annealed at 300°C. We also studied the optical absorption properties of the Li2B4O7 films by the UV-VIS analysis.
