Wavelength Dependent Graphene Oxide-Based Optical Microfiber Sensor for Ammonia Gas

Ammonia detection in ambient air is critical, given its implication on the environment and human health. In this work, an optical fiber tapered to a 20 µm diameter and coated with graphene oxide was developed for absorbance response monitoring of ammonia at visible (500–700 nm) and near-infrared wav...
