“…The calculated direct band gap values of Al -SnO 2 films lay in the range 3.62 eV to 2.63ev for Al doped and un doped SnO 2 respectively. Which are also comparable with the values already reported 3.604 to 4.105 eV [20], 3.87 to 4.21eV [18]. The band gap narrows down due to the decrease in the number of charge carriers with increasing in Al doping and annealing temperature.…”

Al-doped Tin Oxide (SnO 2) nanostructured (ATO) thin films are prepared by Spray Pyrolysis technique on glass substrates Prepared at 400˚C and annealed at 500°C, 600°C. Using a solution consisting of SnCl 4 .5H 2 O starting material and doping source was AlCl 3 with various Al doping ratio. Sn 1-x Al x O 2 (x = 0.04, 0.06 and 0.08) were dissolved in ethanol and stirred four hours at 50˚C. The effect of changes in doping content and annealing effect of Al:SnO 2 nanostructured thin films was investigated. The result of X-ray diffraction has shown that peak located at around 2Ѳ = 37.9° is corresponding to (200) plane which confirmed the presence of SnO 2 in tetragonal crystal system. All the observed characteristic peaks are well matched with the standard data base values. The UV-Visible transmittance figures are clearly depicting that all the prepared thin films are having transparency of 80%, the optical band gap was estimated to be around 2.56ev to 3.6ev. The scanning electron microscopic (FESEM) analyses show the crack-free and dense nature of the thin film formation. The size of the particle was measured from FESEM images and it was found to be in the range of 40-54nm. In AFM the average crystallite size was estimated 45nm and the root mean square roughness value was found to be 20 nm. EDAX to confirm the presence of dopant elements in the nanostructured thin films.

“…The XRD spectra was recorded via d‐spacing value. The XRD (Model: DY‐1656) was operated using 40 KV (Kilovolt) at 2 θ ° 10°–80° in diffraction patterns with Cu K α ( λ = 1.542 A o ), and accelerated with 1°/min counting rate (Baghayeri, Mahdavi, Hosseinpor‐Mohsen Abadi, & Farhadi, 2018; Kannan, Dhanuskodi, et al, 2020; Karthik et al, 2020; Singh & Rajput, 2018).

Microbial mediated synthesis of metallic nanoparticles constitutes as effective and promising approach for the development of antibacterial materials in the field of bioengineering and biomedicine. We prepared Cadmium oxide nanoaprticles (CdO NPs) utilizing Penicillium oxalicum, and cadmium acetate solution via coprecipitate method. The elemental composition and morphology of these synthesized CdO NPs were examined through X-ray diffraction (XRD), UV-Vis absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and Energy dispersive spectroscopy (EDS). Furthermore, we evaluated the bactericidal potential of prepared CdO NPs using Escherichia coli (E.coli), Staphylococcus aureus (S.aureus), Bacillus cereus (B.cereus), and Pseudomonas aeruginosa (P. aeruginosa). Dimethyl sulfoxide was used as negative control while erythromycin was used as positive control. The XRD spectrum revealed cubic crystalline nanoparticles with 22.94 nm size and UV showed absorbance peak at 297 nm with 2.5 eV band gap energy. FTIR depicted O─H and carboxylic groups along with CdO stretching vibration. EDS showed the presence of organic compounds on Cd and O over NPs surface. SEM results revealed the spherical shape of the CdO NPs. The synthesized NPs exhibited highly potent bactericidal activity against selected strains and demonstrated less optical density of 0.086 after 24 hr. Owing to the significant antibacterial activity of CdO NPs, the broad application prospects of these nanoparticles CdO NPs in extensive biomedical applications is indicated.

In this study, zinc oxide (ZnO) nanoparticle was synthesized by a novel route of microwave assisted method using ascorbic acid and PVA as capping agent and stabilizing agent. A prominent peak at 378 nm by UV absorption ensured the synthesis of ZnO nanoparticles. The crystalline property revealed that synthesized ZnO nanoparticle is highly crystalline having wurtzite structure. A significant band at ~ 498 to 557 cm −1 in FTIR was assigned to the characteristic stretching mode of Zn-O bond. EDX spectrum showed that ZnO nano particles were composed only with Zinc and oxygen. SEM image disclosed that ZnO nanoparticles were spherical in shape with an average particle size of 70-90 nm for the combined effect. The antimicrobial and ant-biofilm application of synthesized ZnO nanoparticle was studied against Salmonella typhi, Klebsiella spp. SK4, E. coli RN89, E. coli (gram-negative) and S. aureus-8a (gram-positive) bacteria and exhibited excellent activity against the strains. Prepared nanoparticle also found to possess outstanding photocatalytic activity against methylene blue degradation under sunlight with a T 50 and T 80 value of 71.44 and 165.87 min respectively.
