摘要
Mn1.56Co0.96Ni0.48O4 and Mn2Zn0.2Ni0.8O4 medium-entropy thermal-sensitive films were prepared by a sputtering system. The effects of different annealing temperatures on the microstructure, surface morphology, and optical properties of the films were studied. We obtained films with a cubic spinel structure and dense film surface, and determined their refractive index and extinction coefficient values in the spectral range of 245-1000 nm. Finally, we measured the absorption spectra of both films in the mid- and far-infrared regions.
