عنوان انگلیسی Design and Preparation of Ag2Se Nanostructures and Investigation of Their Physical and Chemical Properties
چکیده انگلیسی مقاله The ongoing research involves the synthesis of nanocomposites incorporated into polymer materials and investigating their linear, nonlinear, structural, and form optical properties for applications in the field of nonlinear optics.  The addition of nanocomposites to polymer materials can enhance and improve many properties, making them appropriate for a wide range of applications. The utilisation of additive nanocomposite manufacturing is highly advantageous in the domain of nonlinear optics (NLO) and its various applications, primarily due to its significant nonlinear response and extensive spectral transparency. Three nanocomposites, namely Ag2Se+PVA, Ag2Se+PMMA, and Ag2Se+PEO, were synthesised using chemical methods. The characterisation of these compounds was performed using XRD, FESEM, EDX, FTIR, RSS, and PL techniques. The UV-VIS spectra were used to study the linear optical characteristics of all the generated samples at various concentrations by adding different polymers. The findings indicated a positive correlation between increasing concentrations and higher absorbance at the same wavelength. Moreover, the Ag2Se+PVA compound exhibited greater absorption compared to the two preceding compounds. The fluorescence of all generated samples was quantified, and the findings indicated an inverse relationship between concentration and fluorescence, whereby an increase in concentration led to a decrease in fluorescence. The nonlinear calculations involved utilising the Z-Scan technique in two scenarios: open aperture and closed aperture. This was done to determine the values of the nonlinear refractive index (n2) and the nonlinear absorption coefficient (β). The Ag2Se+PVA compound exhibited superior nonlinear behaviour compared to the two prior compounds. The tests were conducted using a solid-state pump diode laser with a wavelength of 405 nm and a power output of 2.94 mW.
