“…However, the lifetime of 2AHBC was recorded by varying the quencher concentration in 100% DXN solvent. An increase in the quencher concentration was observed with a decrease in the lifetime of the solute under study. , Figure shows the transient state lifetime decay profile of 2AHBC in 0% ACN + 100% DXN with and without a quencher at room temperature. The lifetime of 2AHBC was biexponential without the quencher and was found to be τ 0 = 1.10 ns.…”

The present study harnesses fluorescence quenching between a nonfluorescent aniline and fluorophore 2-acetyl-3 H -benzo[ f ]chromen-3-one [2AHBC] in binary solvent mixtures of acetonitrile and 1,4-dioxane at room temperature and explores the fluorophore as an antimicrobial material. Our findings throw light on the key performance of organic molecules in the medicinal and pharmaceutical fields, which are considered as the most leading drives in therapeutic applications. In view of that, fluorescence quenching data have been interpreted by various quenching models. This demonstrates that the sphere of action holds very well in the present work and also confirms the presence of static quenching reactions. Additionally, the fluorophore was first investigated for druglike activity with the help of in silico tools, and then it was investigated for antimicrobial activity through bioinformatics tools, which has shown promising insights.

“…The thin films that were prepared using the spin coating technique are often affected by the solvent used. Even if the solvent used has evaporated, both the temperature and chemical properties of the solvent used will always exert an influence on the spin coated thin films [12][13][14][15][16][17] The fingerprint region is from 600 to 1400 𝑐𝑚 −1 and the functional group region is from 1400 to 4000 𝑐𝑚 −1 .…”

Thin films of the polymer, polyvinylpyloridate, reinforced with zinc-nickel ferrite nanoparticles (Zn0.5Ni0.5Fe2O4) and prepared using the technique of spin coating is the central theme of presentation and discussion in this research paper. The zinc-nickel ferrite nanoparticles were used to reinforce a thin film of the chosen polymer and for varying concentrations. The prepared thin films were transparent and consequently studied for the purpose of selection and use in applications specific to the domain of photonics. Optical characterization of samples of the as-synthesized thin films was done using different spectroscopy techniques. Optical density of the as-prepared thin films was obtained using a ultra-violet (UV) spectrophotometer. The reinforcing effect was observed from the emission spectra that was obtained using the fluorescence spectrophotometer. Also, Fourier transform infrared spectroscopy (FTIR) of the reinforced thin films of the chosen polymer was obtained and compared with the unreinforced pure polymer and did reveal an observable change in both the peak value and intensity of the peak. X-ray diffraction (XRD) analysis revealed a noticeable difference in both intensity and crystallization of the thin films of the reinforced polymer. Scanning electron microscopy observations revealed a morphological change of the thin films. Roughness of the sample surface was studied with the help of images obtained from an atomic force microscope (AFM). The present research study technique of spin coating was done properly and successfully. With a gradual increase in the number of reinforcing nanoparticles in the polymer matrix we did observe an increase in Optical Density using UV-Visible spectroscopy. An increase in the Optical Density is beneficial for attaining an improvement in anti-reflection response. This study helped establish the effect of nanoparticle reinforcements on optical properties while concurrently establishing the need for selection and use of thin films for applications in the field of photonics.
