| Summary: | Synthesizing Zinc Oxide (ZnO) nanorods by
varying the growth duration will give effect to the morphology
of ZnO nanorods which were grown by using microwave
assisted hydrothermal method. The effect of different growth
duration from 4 to 10 hours is investigated on the surface of bare
silica optical fiber. The buffer coating of a silica fiber is stripped
off for 5 cm to expose the area for the growth of ZnO nanorods.
The ZnO nanorods were grown on the fiber by dipping the fiber
into the prepared growth solution in a 90˚C microwave assisted
hydrothermal synthesised. The physical characterization
through field emission scanning electron microscopy (FESEM)
results show the diameter of ZnO nanorods is about 75.0 - 93.8
nm and the length of ZnO nanorods ranges from 666.2 nm to
978.6 nm according to their growth duration. The uniform
growth of 43.33 nanorods/(µm)2 reveals that the 10 hours of
growth duration performs the highest density growth of ZnO
nanorods. The amplified spontaneous emission (ASE) peaking
at 1550 nm is used to investigate the effect on the light intensity
in the optical fiber with coated and uncoated ZnO for optical
characterization. The ASE spectrum shows that the light
intensity decreases with the growth durations due to the light
scattering effect. |
