The coated thin ﬁlm was annealed at 200 and 400 °C temperatures, respectively. The XRD investigation on the thin ﬁlm at three different temperatures have been carried out and their results showed that, the maximum peak intensity of (200) plane was observed at 400 °C than rest of the two samples. In addition to that, it was also found that, the annealing process has certainly improved the crystallization of the ﬁlm particularly at 400 °C. The SEM and TEM results conﬁrmed that the particle size in the range of 30–50 nm. The peaks corresponding to the Ag and O in EDAX spectrum ensure the ﬁlm is purely made up of nano-Ag 2 O and the presence of Sn was also conﬁrmed by its respective peak. Additionally, vibrational analysis and Raman spectroscopy was carried out in this work to conﬁrm the modes of vibration of the NPs. Sensitivity analyses was carried out to test the sensing capacity of the powder.

Among the various nanoparticles, the noble metal nanoparticles, especially silver (Ag) particles have been the main area of focus of the scientists because of their fascinating physical and chemical properties (Leonard et al. 2011; Sinha et al. 2015). Silver has been valued throughout history for many of its properties that are useful to humankind. It is used as a precious commodity in currencies, ornaments, jewelery, electronic contacts and photography, among others. One of the most beneﬁcial uses of silver has been as a potent antibacterial agent that is toxic to fungi, viruses and algae. Silver has long been used as a disinfectant; for example, the metal has been used in treating wounds and burns because of its broad-spectrum toxicity to bacteria as well as because of its reputation of limited toxicity to human. Development of new nanomaterials with metal nanoparticles (Ag, Au, Cu, Rh, Pd, etc.) deposited on glass surfaces, have gained much attention in material science because of their expanding applications; composites in optics, medical diagnostics, analytical chemistry, catalysis, photo catalysis, etc. Argentous oxide can be described as silver oxide or Ag 2 O. Metal oxides in the Ag system; Ag 2 O, AgO, Ag 3 O 4 and Ag 2 O 3 constitute a fascinating group of inorganic oxide materials. Silver oxides crystal- lized in various types of crystal structures which are having variety of interesting physico chemical properties such as catalytic, electrochemical, electronic and optical proper- ties. Therefore, silver oxide nanocrystals and thin ﬁlms have been intensively pursued for promising applications & A. Ayeshamariam aamariam786@gmail.com & N.
