Résumé
Lanthanoid carboxylates were synthesized, in situ self-assembled in primitive crystals to illustrate temperature-driven evolution in chromaticity. Evolution in structure (crystallinity), composition, luminosity and chromaticity investigated revealing the coupled role of divergence in order/structure (spatial organization), and composition in tuning observed color. Loss of crystallinity or increase in residual carbon leads to decrease in luminosity even with increase in hue. Comparing Ho and Er congeners shows that the density of accessible transitions relates to shifts in low and high wavelength components of color. This work demonstrates that, just as interface dipoles can lead to change in semiconductor bandgap, structure and composition can analogously alter observed color.
