Structurally integrated luminescence based oxygen sensors with Organic LED/ oxygen sensitive dye and PECVD grown thin film photodetectors

TL;DRAbstract

There have been increasing efforts for the development of compact and miniaturized oxygen sensor for various applications including multianalyte sensor and sensors with a reliable and accurate monitoring of oxygen concentration in controlled environments requiring measurements under low oxygen concentration. This work has been devoted to the development of structurally integrated luminescence quenching based sensors, the structure comprising of Organic Light Emitting Diode (OLED) as excitation source, oxygen sensitive dyes as the sensing element and PECVD based thin film photodiodes for detection. The whole structure can also be extended towards the development on flexible substrates. The developed sensor is less cumbersome and bulky and easy to use compared to the existing sensors. The commonly used Clark electrode for measuring dissolved oxygen suffers from interference from the ambient, requires frequent maintenance and electrolyte change, and also consumes oxygen during the measure
