Using electroluminescence as a metrology method could have many advantages for on-chip characterization of chemical composition, where the need for an on-chip light source can be eliminated and materials with different excitation energies can be characterized by the same device. However, the range of materials that can be used in electroluminescent devices is typically limited due to challenges related to material processing and band alignment. In this project, we aim to develop a multiplexed electroluminescent device that can produce electroluminescence from infrared to ultraviolet wavelengths, immediately after deposition of the emitting material and without the need for further device modifications. Such a device may enable the use of electroluminescence spectroscopy to probe chemical reaction kinetics and dynamics.
