Optical Hydrogen Sensing Based on Hybrid 2D MoO3/Au Nanoparticles


© 2015 The Authors. Published by Elsevier Ltd. In this work for the first time, we report the use of molybdenum oxide (MoO3) nanoflakes on gold as active material for plasmonic optical gas sensor. The M0O3 flakes were deposited over a monolayer of gold nanoparticles, chemically attached to a functionalized fused silica substrate. The coupling between MoO3and gold nanoparticles led to reversible optical changes of the localized surface plasmon resonance of gold nanoparticles upon exposure to H2.
