Abstract
ZnO network is considered as a good visible blind UV light detector. In this study we report
room temperature UV detection analysis at three different wavelengths spread in UV-A and UV-B
regions. Studied ZnO network is prepared by one of the most efficient methods: flame transport
synthesis. ZnO network between two interdigitated electrodes were irradiated by UV radiation
of three different wavelengths as 400nm, 370nm, and 280nm. The result analysis exhibits UV
response of ~ 32, 28, and 11 at wavelength 370nm, 280nm, and 400nm, respectively. The UV
response characteristics were measured and get analysed in detail with its sensing mechanism,
correlating slow regeneration or decay time (~7.9s) to slow exchange of carrier’s movement due
to trapping of carriers by oxygen ions. The detailed sensing mechanism has been discussed.
