RESEARCH HIGHLIGHT
Deliquescent Chromism of Nickel(II) Iodide Thin Films
In a recent collaboration paper, Tim Siegler, Mokshin Suri, and Michael Abney, alongside a team of collaborators from the Milliron Group lead by Lauren Reimnitz, observed and studied a new phase change in thin films of nickel iodide. Showing that water vapor uptake could reversibly convert NiI2 films of under 10 microns in thickness from a dark brown to an optically clear state, we demonstrated how nickel iodide thin films in ambient humidity have potential application in thermochromic smart window materials with color neutral transitions. This unique approach turns a problem common to many transition metal halides - humidity instability - into a feature, taking advantage of the color change of this degradation process. Find the paper, recently published in Langmuir, at this link.
