Researchers have explored a fascinating cooling phenomenon within halide perovskite-based “dots-in-crystal” materials, uncovering both their promise and challenges.
In a groundbreaking study, scientists from Chiba University investigated the potential of solid-state optical cooling through perovskite quantum dots. Central to their research was anti-Stokes photoluminescence, a rare process where materials emit photons with higher energy than those absorbed. This innovative approach could transform cooling technology, offering a path to more efficient, energy-saving solutions. Their work not only highlights the immense promise of this technique but also reveals key limitations that pave the way for further advancements in the field.
