Subsequently, we measured the ultraviolet-visible spectrophotometer, analyzed the maximum absorption spectrum of the sample in the wavelength range of 190nm, and then studied the energy gap band. EG), and its value is equal to 5. Compared with tidal research, the research results show that the research value is about 5. 5 to 56 electron volts, which is the research in this paper, shows that the energy difference of this material is dielectric material.
