The prime goal of this work is to synthesize free-standing polyvinyl alcohol (PVA) films doped with Ag2S, CuS, Ag2S/CuS alloy, and Ag2S/CuS nanocomposites through the sol–gel route. The dependence of Ag2S content in the ...

Toward the need for solid-state fluorescent quantum dots, resistant to self-quenching, we describe a solvothermal-assisted sol–gel method to synthesize Se quantum dots. Morphological and crystalline characterizations reveal ...

Thermally induced optical nonlinearity of the laser dye LDS 867 is studied in ethanol solution using the self phase modulation and closed aperture z-scan techniques, employing a continuous wave low power He-Ne laser beam ...
