Abstract

Opto-electrical characterization of LEDs/OLEDs is of essential importance for thorough understanding of light generation and emission properties of light emitting materials as a response to an applied electric current. The combination of photoluminescence (PL) and electroluminescence spectroscopy techniques can reveal the relationship of structure-lighting properties of novel LED/OLED materials and whole devices. Without doubts, this can help to optimize the composition and as a result the performance (brightness, lifetime, color) of these devices.
