Abstract :
We developed a variable multi-color microfluidic organic light emitting device based on mixing of different electrochemiluminescence (ECL) solutions. The prototype of microfluidic device consisted of Y-shaped SU-8 microchannels sandwiched between polyethylene naphthalate (PEN) and glass substrates having indium tin oxide (ITO) anode and cathode pairs. 5,6,11,12-tetraphenylnaphthacene (rubrene) and tetraphenyldibenzoperiflanthene (DBP) doped rubrene were used as ECL materials. Yellow, red, and orange color emissions from the ECL cell were obtained by changing DBP concentration in rubrene solution. Multi-color ECL was confirmed from the fabricated Y-shaped microfluidic device before and after mixing of ECL solutions.
