Non-Invasive Probing of Time-Dependent Ion-Distribution Profile in Light-Emitting Electrochemical Cells by An Advanced Confocal Microscope

Abstract

Herein, we propose a pure optical design studying the spatial ion-distribution of organic films in light-emitting electrochemical cells, which can be further used to observe numerous ion-distributions inside organic/inorganic materials, Li-ion batteries, or micro-fluid channels.
