Synthesis of colourless silver precursor ink for printing conductive patterns on silicon nitride substrates

► A stable and colourless silver precursor ink has been synthesised for directly printing silver conductive patterns with a common colour ink-jet printer. ► The resistivity of silver conductive films deposited using 20 printing cycles was 3.1 μΩ cm, which was twice as high as that of bulk silver. ► The low resistivity of silver patterns suggests applications for ink-jet printing of electronics devices.
