Zusammenfassung:The synthesis of Ag‐doped ZnO nanorod employing hydrothermal process over modified cladd optical fiber is reported. The developed material is characterized using X‐ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR), X‐ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), and Brunauer‐Emmett‐Teller (BET) analysis to evaluate the morphology and the nature of nanorod formed. The initial performance of the coated modified clad optical fiber toward detection of ammonia gas in aqueous solution is also presented. The sensing performance revealed that the developed material possess improved sensitivity toward ammonia gas at room temperature compared to Ag doped nanowires containing optical fiber sensor. Ag‐doped ZnO nanorods around 100 nm size grown employing hydrothermal technique over modified clad fiber. Such kind of nanorods growth over modified clad fiber based the sensor shows improvement in sensitivity for ammonia sensing than Ag‐doped ZnO nanowires due to the enhancement of surface area showing the maximum sensitivity (%) of 0.435 at room temperature.
