Cooling With Light: Solid-State Optical Cooling Using Quantum Dots

https://www.eurekalert.org/news-releases/1065953 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 […]
