N2 - We proposed color-tunable microfluidic electrogenerated chemiluminescence (ECL) cells. A Y-shaped electro-microfluidic device, which consists of two inlet and one mixing channels, was fabricated to investigate variable multi-color emissions induced by mixing two different ECL solutions. 5,6,11,12-Tetraphenylnaphthacene (rubrene) and tetraphenyldibenzoperiflanthene (DBP)-doped rubrene solutions were used as liquid emitters. Yellow (rubrene) and red (DBP) ECL emissions were observed in the inlet channels before mixing, whereas the mixed solution exhibited orange emissions. This is because the DBP concentration was changed facilely in the mixing channel, which leads to the tunable ECL emission. The proposed device will be promising candidates for unique light-emitting applications.
