Cold sintering of hybrid copper-iodides in transparent ceramics using dolomitization-inspired densification (opens in new tab)

The non-toxic hybrid luminescent copper(I) iodides are competitive solution for environmentally sustainable applications in solar cells, lighting, and detectors. However, their susceptibility to elevated temperature and oxidation creates great hurdles for technological integration due to the lack of suitable encapsulation. Inspired by the mechanism and kinetics of dolomitization in geology, we propose a cold sintering process that enables the densification of highly transparent SrF2 ceramic a...
