Optimization of Thermal Emittance Tuneability of La (Sr, Ca)MnO₃ Thin-Film Materials in 173-373 K

Abstract:

For the purpose of maximizing the thermal emittance variation of La (Sr, Ca) MnO₃ thin films in the temperature range 173-373 K, thin film optical mechanism and mathematical optimization method were used to determine the thin film structure, including substrate type, thin film chemical composition and the optimized film thickness. The optimization results indicate the variation amplitude of La (Sr, Ca) film infrared emittance reaches to 0.62, which is 35% more than that of ceramic type smart radiation materials. The designed thin film structure can be used to enhance the thermal control efficiency of spacecraft greatly.
