A Keithley 2400 source-meter unit was used for the luminance–current density–voltage measurement. All LEDs were measured from zero bias to forward bias at a rate of 0.05 V s−1. The luminance of the LEDs was calculated on the basis of the EL spectrum and the spectral response of...
detector, sometimes referred to as time-encoded FD-OCT (TEFD-OCT) or swept source OCT, or, alternatively, a broadband source and spectrally resolving detector system, sometimes referred to as spectrum-encoded FD-OCT or SEFD-OCT. These three OCT techniques parallel the three spectroscopy ...
