Spectrum of a typical pcLED using HALOs.
(a) Integrated and emission efficiencies in a HALO coated pcLED vs pulse length with a pulse period. The solid lines are the calculated efficiencies using the integrated solution to Eqs. (1)–(3).
(a) and luminescence in a HALO pcLED with a pulse length. The decay in the pcLED is compared to the decay in a low intensity spectrometer measurement. (b) luminescence buildup in a HALO pcLED using a pulse period of and pulse length of vs a calculated buildup curve from the integrated solution to Eqs. (1)–(3) and in the absence of saturation.
Schematic of (excited)– (excited) and (excited) ET quenching processes. The transitions marked with “X” are nonradiative transitions.
