Introduction of chirality and adjustment of three primary colors. a Schematic diagram of chiral-controlled energy transfer. b Transmission CD spectra of R-(NEA)₂MnBr₄, S-(NEA)₂MnBr₄, and RAC-(NEA)₂MnBr₄ films and the corresponding absorption positions. c Variation trend of blue and green PL lifetimes before and after the introduction of chirality. d Under variable temperature conditions, the green light emission of RAC-(NEA)₂MnBr₄ shows a blue shift (I), and the green light emission of chiral-(NEA)₂MnBr₄ remains stable at 540 nm (II). e PL spectrum and corresponding optical photo of chiral (NEA)₂MnBr₄ film with three excitation peaks of equal intensity. f CIE coordinates of dry and wet (NEA)₂MnBr₄ film under different excitation wavelength. The red curve is the color gamut distribution of the dry sample, and the green curve is the color gamut distribution of the wet sample. (Color figure online)
