Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

open access: yesEcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Flexible electrochromic windows: a comparison using liquid and solid electrolytes

open access: yesJournal of the Brazilian Chemical Society, 1999
In the present work, two electrochromic devices (or electrochromic windows) based on intrinsically conducting polymers were assembled and characterized. For both devices, the materials used on the assembling were the same except for the electrolyte layer.
