| description |
A Hydrogen (H2) gas sensor was successfully
developed using optical fiber coated with Zinc Oxide (ZnO)
nanorods. The single-mode fiber (SMF) used as a sensing device
has been prepared by etching the SMF fiber and coated with
ZnO nanorods. The etching of the fiber was performed using
hydrofluoric acid (HF) to enhance the evanescent field around
the fiber core. The ZnO nanorods were prepared by
hydrothermal method through seeding and growth solution
technique. The diameter of cladding and core are 125 µm and 8
µm, respectively, before etching and goes down to 11 µm after
etching. Around 2 cm of ZnO nanorods were coated in the
middle of the etched fiber. The sensing layer was characterized
through Scanning Electron Microscopy (SEM), Energy
Dispersive X-Ray (EDX) and X-Ray Diffraction (XRD) to verify
the properties of ZnO. The developed sensor’s response and
recovery time were observed to be 7 min and 3 min, respectively,
for a low concentration of 0.25% H2 gas. The aim of this study
is to understand the gas sensing properties towards the spectral
intensity variations in etched optical fiber coated with ZnO
nanorods.
