Performances of CP-LEDs based on a cluster with TCTA incorporating. (a) Energy band alignment of the CP-LED with TCTA incorporation. (b) Luminance–voltage–current density curves of the CP-LEDs with different weight ratios of TCTA. (c) EL spectra of the CP-LED with 20 wt % TCTA incorporation. (d) EQE–luminance curves and (e) statical maximum EQEs of the CP-LEDs with different weight ratios of TCTA. (f) Summary of the EQEs of the LEDs using clusters or cluster complexes as parts of the emitting center (data in the figure are listed in Table S4). (g) CPEL spectra and (h) g_EL versus wavelength curves of the CP-LEDs based on Cu₂Au₂(R/S-BTT)₄ with 20 wt % TCTA incorporation. (i) Summary of EQEs and |g_EL| for CP-LEDs in the literature and our work (data in the figure are listed in Table S5).
