Electrochemiluminescence (ECL) is a process where light is emitted through electrochemical reactions involving luminophores, and this concept is utilized in a new type of device called an ECL device (ECLD).
A model was created to understand how the transport and reaction rates of these luminophores affect the brightness of ECLDs when driven by alternating current voltage.
The study reveals that while increasing operational frequency (f) initially boosts brightness by enhancing reactions, at very high frequencies the effectiveness decreases due to slower reactions at the electrodes.
