Electroluminescence (EL) is the direct conversion of electrical energy into light through radiative recombination of holes and electrons in a material. This phenomenon is commonly seen in both inorganic semiconductors, like GaAs, and organic semiconductors (OLEDs), and it powers numerous lighting and display technologies due to benefits like low energy use, long life, and a wide range of color emissions. EL devices, such as LEDs and OLEDs, are increasingly used in medical, industrial, and environmental applications, creating a demand for tools capable of accurately characterizing their emission properties.
The Fluorolog-QM™ by HORIBA offers a robust solution for characterizing electroluminescent materials. With its modular design, this spectrophotometer can perform timeresolved EL (TREL) and basic steady-state measurements on EL samples without requiring additional external equipment. Here, we demonstrate how the Fluorolog- QM enables accurate TREL measurements over a wide range of lifetimes and supports steady-state EL spectra acquisition.
