Using Quantum Dots for solid-state optical cooling

Researchers investigate an elusive cooling phenomenon in a halide perovskite-based "dots-in-crystal" material, shedding light on its strengths and limitations

Researchers at Chiba University have proposed a novel approach to using quantum dots based on perovskite materials for solid-state optical cooling. But Quantum Dots are relatively unstable and easily degrade on exposure to light and air. Therefore, the team proposed a stable structure in a special arrangement of perovskite quantum dots; dots-in-crystals. Since using quantum dots in semiconductors is still a mystery, this study could pave the way for future researchers to focus on improving the cooling performance.
