Mo/Si multilayer are normally used in the early extreme ultraviolet (EUV) astronomical observation. In recent years people want to get observations in higher spectral resolution. Multilayer with low=Z materials have been studied. Four kinds of multilayer, Mg/SiC, Si/SiC, Si/B4C and Si/C multilayer were designed at the wavelength of 30.4 nm and compared with the normal Mo/Si multilayer. All the multilayer were prepared with DC magnetron sputtering, and their reflectivities were measured by synchrotron radiation. The results show that the bandwidth of Mg/SiC multilayer is 1.44 nm, which is the smallest, and the reflectivity is 44%, which is the highest. While the reflectivity of Mo/Si multilayer is only 24% and the bandwidth is 3.11 nm. The bandwidths of multilayer of low=Z materials are narrower than that of the normal multilayer. Therefore, multilayer of low=Z materials can be used in the EUV high spectral resolution field.
