Perovskite made up of alternating organic/ inorganic layers squeezed between two diamonds shows improved light-handling capabilities

"interaction between layers determines how material absorbs, emits, controls light... applying pressure significantly increased photoluminescence (brightness)... continuous tunable color: green to yellow to red... applying very large pressure made it started glowing differently, signaling improved light handling... squished more in 1 direction than others causing internal structure became less twisted unlike similar materials becoming more twisted... optics/ electronics tuned/ optimized toward devices like LEDs, PVs"
