FIG. 2.

(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).

FIG. 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.
