By leveraging the synergistic competition between phenylethylammonium bromide (PEABr) and propylammonium bromide (PABr) ligands, we achieve optimized phase composition with suppressed formation of small-n phases (n ≤ 3) while promoting dominant emission from larger-n phases, thereby minimizing energy funneling losses during interphase energy transfer. The optimized dual-ligand system (1:1 PEABr:PABr ratio) yields blue-emitting PeLEDs demonstrating remarkable performance metrics: stable electroluminescence at 485 nm with a peak external quantum efficiency of 7.3 %, maximum luminance of 755 cd m<sup>−2</sup>, and operational lifetime (T<sub>50</sub>) of 660 s at initial luminance of 100 cd m<sup>−2</sup>.
