The major purpose of LED is the electroluminescence. We use the time-resolved electroluminescence (TR-EL) method to measure the response time of LED in our experiments. In addition, typical diode has optical beam induced current (OBIC) characteristic in its depletion region. Combining upon physical reaction we can compare TR-EL and OBIC in the same LED. We are using the high frequency function generator, pulsed laser with high repetition rate, laser scanning confocal microscopy and a high frequency phase sensitive lock-in loop to achieve temporal resolution. The response time of LED can be measured in two different physical characteristic.
