Abstract

Abstract : 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 number1700047, 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.
