Abstract

This work presents a Low Temperature Co-fired Ceramics (LTCC) microreactor with integrated heater and optical window for reaction monitoring. This fabrication procedure enables the integration of both heater and optical window in an all-ceramic monolithic microfluidic device, thus achieving the advantages of homogeneous surface chemistry and physical properties, the integration of electronics and transparency to monitor a chemical reaction. Carbon Dots (CDots) were synthesized at high temperature and pressure (190 °C and 17 bar) in aqueous solution. The reaction progress was followed by means of fluorescence imaging and the CDots obtained presented a quantum yield (QY) of 0.75.
