Sr-doped lanthanum manganite (La1-xSrxMnO3) is characteristic of thermochromic, which can act as a smart thermal control material used in the variable-emittance devices. In the present study, La1-xSrxMnO3 thin films were prepared on MgO(100) substrates by pulsed laser deposition, and the effect of Sr-doping (x = 0 ~ 0.4) on the structure and infrared emissivity was investigated. Single-phased La1-xSrxMnO3 films with (100)-orientation were obtained, which showed a dense texture with smooth surface. The ratio of Mn4+/Mn3+ in the films was increased with increasing Sr doping, leading to the enhancement in double-exchange interaction and electrical conductivity. As a result, the phase transition from metal to insulator was observed with the increasing of test temperature. For the La0.8Sr0.2MnO3 thin film, a large value of emittance (De = 0.28) was obtained, indicating good variable-emittance by appropriate Sr doping.

In this paper, we report a study on the infrared stealth properties of cotton fabrics with ZnO: (Al,In) coating. Al, In doped ZnO samples were prepared through sol-gel method. The crystalline phase of the ZnO: (Al, In) solids were determined by XRD. IR-2 Dual-Band Infrared Emissivity Measuring Instrument was used to test the infrared emissivity of the coated fabric. Infrared stealth effect of ZnO: (Al, In) coated fabric was measured using thermal infrared photospectrometry instrument. It was found that the ZnO: (Al, In) thin film has a low infrared emission in the range of 8 ~ 14μm wavelengths, and the addition of Al and In leaded to a better infrared stealth effect.
