“…The observation demonstrates that there is a proportional enhancement of the refractive index in both the nanorods and the sensing zone as a result of a boost in the concentration concerning zinc oxide nanorods [41,42]. When light travels along a directed path within a certain platform, an important proportion of that light extends beyond the platform's boundaries [30]. This occurrence leads to increased sensitivity when detecting variations in the refractive index of the sensing region.…”

“…The glass substrates were submerged in acetone [CH 3 COCH 3 ] (Bendosen Laboratory Chemical, Germany), utilising a water bath technique for 15 minutes to eliminate organic matter. Subsequently, the substrates were inserted into a vacuum oven maintained at 90 ℃ for 1 hour [30]. Subsequently, the fabrication of ZnO nanorods coating using hydrothermal techniques was performed on every samples [31].…”

An optical characterization of the proposed sensing scheme comprises of ZnO nanorods coated glass substrate based on side coupling technique for different scattering area is reported. The glass substrate was coated with a highly responsive nanomaterial which is Zinc Oxide (ZnO) nanorods using hydrothermal technique. The scattering area were varied into five samples of 0.016m 2 , 0.018m 2 , 0.020m 2 , 0.022m 2 and 0.024m 2 . The samples were exposed to a range of RI solutions spanning from a concentration of 0% to 100%. Based on experimental results, the sample with an area of 0.022m 2 exhibited outstanding characteristics in most of the performance parameters such as α, γ, output light intensity and sensitivity towards different RI solution. The sample demonstrates a notably elevated level of light intensity and output voltage in comparison to the closest best samples by a factor of 1.1. Besides it produced linearity of 97.5% and sensitivity of 0.0125V/%. The proposed sensor exploits the visible light using the side coupling technique applied on the glass surface that was coated with Zinc Oxide (ZnO) nanorods to enhance the output coupling voltage. It effectively employed the scattering and surface absorption properties to interact with different refractive index solutions INDEX TERMS ZnO nanorods, glass substrate, scattering area, refractive index, side coupling

<div>This paper reported an optimized hydrothermal synthesis technique to grow zinc oxide (ZnO) nanorods vertically on the normal microscope glass. ZnO nanorods exhibited various advantages such as strong binding energy, non toxicity, large surface to volume ratio and versatility for optical detections. However, the growth of nanorods which aligned vertically on the glass substrates is rather complicated. It required a thorough process based on optimized concentration, growth duration, growth temperature and solvent variations. The morphological structure result has shown an exceptional vertical growth of the nanorods on the glass surfaces which increase the nanorods density. The optimized synthesis technique produced high density ZnO nanorods up to 3 𝑥 10<sup>13</sup> nanorods/m2 which is double as compared to conventional synthesis technique.</div>
