Fig. 4

A Solid-state luminescence spectrum under excitation at 365 nm (D represents the quintet; F represents the septet). B The decay curve of 5D0 energy level in solid-state R-Eu-Et-1/2. C Schematic diagram of the Jablonski energy levels in different states. D The electron cloud density maps of R-Eu-Et-1/2 by DFT theoretical calculation (GGA-PBE/DND). E, F CD spectra of R/S-Eu-Et-1 and R/S-Eu-Et-2 dispersed in CH3CN solution. G, I CPL and DC spectra. H, J corresponding glum values. Note: The green and yellow balls represent excitons; Abs. Absorption, FL fluorescence, Phos. Phosphorescence, ISC intersystem crossing, ET energy transfer.
