Communication—Screen-Printed Silver Electrodes for Enhanced Performance in Light-Emitting Devices Based on Electrochemiluminescence

Electrochemiluminescence (ECL) based on a series of electrochemical processes of luminophores has attracted interests as a new light-emitting device platform referred to as the ECL device (ECLD). Here, we investigate the electrical and luminescence properties of ECLD with silver (Ag) electrodes. It is found that ECLD with screen-printed Ag electrodes prepared from carefully selected Ag paste ink could yield higher luminescence than that with thermally-evaporated Ag thin-film electrode. The results indicate that the low-cost large-areal printed ECLD potentially has comparable or surpassing performance to conventional vacuum-processed ECLDs. (C) The Author(s) 2019. Published by ECS.
