Abstract

(002)-oriented ZnO nanostructure for NO gas sensing application was successfully grown
on glass substrates by two-step processes, which are seeding process via dip-coating method using
diethanolamine (DEA) as chelating agent and growth process via chemical bath deposition (CBD). The samples
were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission
electron microscopy (TEM). Two ZnO �lm samples, named samples A and B, were fabricated without and
with DEA addition in the seeding process, respectively. XRD observation results show that ZnO �lm was
successfully deposited on both samples, where sample A has a random crystal orientation; while sample B
has a very dominant (002) orientation. Further, the selected area electron diffraction (SAED) observation
with TEM con�rmed that sample A has a random orientation indicated by a ring-shaped diffraction pattern;
while sample B has a hexagonal crystalline structure diffraction pattern which is oriented towards the
normal direction of the substrate surface, indicated that ZnO �lm was grown along this (002) orientation for
sample B. SEM images of both samples showed that the ZnO �lm is ZnO nanorods with hexagonal wurtzite
structure shape and sample A is clearly more randomly oriented than sample B. During the investigation of
NO gas sensing performance, it is found that the highest response towards NO gas was occurred at a lower
operating temperature of 200�C for sample B compared to a higher operating temperature of 300�C for
sample A. Furthermore, sample B has a higher dynamic gas response and sensitivity than sample A. These
results indicate that the (002) oriented ZnO �lm has a better performance than the randomly oriented ZnO
�lm as NO gas sensor.
