Optimizing Scattering Area of ZnO Nanostructures on Glass Substrates Platform for Sensing

This paper presents an optimization of scattering area on a glass substrate platform for a proposed sensing method. The glass substrate was coated with sensitive nanomaterial, which is Zinc Oxide (ZnO) nanorods. The hydrothermal technique was employed to fabricate the ZnO nanorods on microscope glass substrates of varying areas. The samples undergo exposure to various levels of RI solution, ranging from 0% to 100% concentration. This was performed to examine several performance parameters, including the scattering coefficient, and sensing performance factor that generated by the proposed sensor. The growth area of 0.022m2 demonstrated the most favorable samples with respect to the concentration level. It exhibited normalized scattering coefficient (α) and normalized sensing performance factor (ɣ) close to 1 which is desirable in this study.
