Upon cooling and heating, organic–inorganic perovskite nanoparticles are reversibly decomposed and formed through the lower‐critical‐solution‐temperature phenomenon. Akinori Saeki and co‐workers demonstrate an aurora‐like photoemissive object in article number 1700047 , and reveal the roles of the involved chemicals (methylammonium cation, lead, halogen, and molecular additives). The cloud temperature is varied from ca. 30 to 80 °C by controlling the concentration, and multi‐luminescent‐color thermoresponsive solutions are achieved through compositional engineering of the halogen.
