Résumé :	"The main objective of this thesis is to provide a new protocol that permits the detection of the spin crossover (SCO) phenomenon in a single nano-object. To accomplish this, we propose luminescence as a highly sensitive technique that may be employed at scales where other conventional methods are no longer effective. We aimed to develop SCO nano-materials with luminescence properties in order to isolate these objects, address them and then probe their properties via luminescent detection. Methods ranging from random to directed microcappilary assembly of SCO nanoparticles and also in situ synthesis of isolated luminescent SCO objects (ca. 150 nm) based on soft lithographic techniques were explored. At the same time, their investigation in fluorescence microscopy is shown and the experimental challenges that this task imposed are discussed. Also, the potential application of these hybrid materials in microthermometry is studied. As a proof of concept, thin films of luminescent SCO systems were employed to obtain thermal cartographies of gold micro - nanowires heated by Joule effect."
