Abstract

An approach is presented for measuring the dynamic variations in refractive index (RI) of Graphene Oxide (GO) based optical gas‐sensors [1‐ 3] upon their exposure to gases, using thin‐film interference method [4]. The approach is simple yet effective, and also is physically integratable into the sensing system, a required attribute for being able to measure the dynamically changing RI in response to the ongoing interactions with the analyte. The details can be found in our journal paper [5].
