Abstract
Nd0.3Sm0.7NiO3 exhibits a reversible metal semiconductor phase transition which is, in the infrared range, responsible of a thermo-optical contrast. The variation of the thermal emittance for Nd0.3Sm0.7NiO3 ceramic was measured, in the mid-infrared range, by using reflectance measurements and on a benchtest. The thermo-optical effect of the sample was measured in situ by thermal imaging camera. The emissivity contrast obtained is 18% between 293 and 373 K which induced a difference of 27 K between the real and the visible temperature at 373 K.
