Tuneable emissivity ceramics and coating in the infrared range

Transition metal oxide materials are finding many applications in electronic and optical devices due to their wide range of electrical, magnetic, and optical properties. Among these interesting properties, the optimization of thermochromic switching in the infrared range is challenging. One of the potential applications of thermochromic IR coating is their use in the field of the IR discretion or furtivity. The concept of thermal furtivity is the ideal situation when an object or a material is undetectable whatever its temperature, comparatively to the observed background, which is supposed to be at constant temperature. In other words, the object and the background have ideally the same emittance whatever the temperature of the object, at least in the detection band of the camera. This situation can be approached if one considers an adaptative material with partial emissivity in band II or III decreasing with temperature. Thus, materials with a low temperature, semiconductor like behavior, and a high temperature metallic state, with a transition temperature adjustable around room temperature, are good candidates for such applications.

The manganite system
In recent work [Appl. Phys. Lett. 89, 081909 (2006), Appl. Phys. Lett. 93, 151910 (2008)], we showed that electron doped (Sm1−x,Cax)MnO3 perovskite manganite are potential infrared thermochromic materials and we have measured the thermal emittance changes at the charge ordering transition of (Sm0.35Ca0.65)MnO3. This property was evidenced in bulk ceramics [Appl. Phys. Lett. 89, 081909 (2006), Appl. Phys. Lett. 93, 151910 (2008)] and more recently in Sm0.5Ca0.5MnO3 films [J. Appl. Phys. 111, 113517 (2012)].

The nickelate system
The rare earth nickelate perovskite ReNiO3 has been strongly investigated in the past due to its metal insulator transition easily controllable by changing the rare earth nature. Such compound are however difficult to synthesize, an often need high oxygen pressure for the stabilisation of Ni3+.
In recent work, [Journal of solid state chemistry, 183 (2010) 1663-1669] by using polymeric precursor associated with moderate pressure annealing, we showed that it is possible to obtain rare earth nickelates with metal insulator transition. The perovskite structure was confirmed by electron diffraction and high resolution electon microscopy. The thermal infrared characterization confirmed the metal insulator transition.

Slight contrast differences can be observed in the [0 1 0] oriented images for the Nd0.3Sm0.7NiO3 prepared at 20 bar.
