| Description |
Français : Cette image (fausses couleurs) révèle l'apparence du pigment thermochromique observé en stéréomicroscopie optique à froid, en dessous de la température de transition de couleur de 28 ° C (Fig. a) et à une température plus élevée (Fig. b). Les poudres ont été déposées sur un support coloré en rouge, pour mieux apprécier leur évolution chromatique en fonction de la température appliquée. Les deux images mettent en évidence la transition de couleur pertinente des sphérules de l’état noir à l’état transparent au-dessus de la température seuil de 28 °C.
English: This picture reveals the appearance of the thermochromic pigment observed with the optical stereomicroscope in the cold state, below the color transition temperature of 28 °C (Fig. a), and at higher temperature (Fig. b). The powders were placed on a red colored support, to better appreciate their chromatic change as a function of the applied temperature. The two images highlight the relevant color transition of the spherules from the black to the transparent state above the threshold temperature of 28 °C. |
