Résumé en anglais

We demonstrate that the interaction of a CO2 laser with a host matrix, in which spin-crossover compounds are diluted, makes it possible to induce a low-spin-to-high-spin transition. The phenomenon is demonstrated for two different compounds diluted in a commercial polymer. The photo-induced transition is due to laser-induced heating of the host-matrix, which results in a localized modification of the properties of the sample. This phenomenon is reversible, and its kinetics are well accounted for by a simple model. This process makes it possible to write optical information at a high speed and to erase it in such materials.< Réduire
