Transparent UV-to-red WCM film equipped with a Eu3+ luminophore. (a) Schematic of plant growth acceleration using WCM film (left) and molecular structures of [Eu(hfa)3(TPPO)2] and TDMPPO (right). (b) Photographs of agriculture film painted with or without WCM under daylight (upper) and UV irradiation (lower). (c) Solar spectra obtained without (black line) and with the WCM film (solid colors).
