Integrated PL, EL and EPL intensities and gain as a function of applied voltage. (a) Integrated emission intensities for PL, EL and EPL are measured as a function of applied voltages, together with the calculated EL + PL and EPL-(EL + PL). (b) Gain is plotted as a function of applied voltages at T = 14°C.
