OPTICAL CHARACTERIZATION of STEARIC ACID POWDER and ITS USE for THE SYNTHESIS of NANOPARTICLES

Fatty acids are found in the structure of triglycerides and phospholipids which have vital importance for life. Stearic acid is an important member fatty acids. It used manufacturing various products such as soaps, detergents, rubbers. valuable to provide a thermal optical characterization database stearic acid. In this study, comprehensive has been prepared by studying thermogravimetric analysis, X-ray powder diffraction, dispersive Raman Fourier transform infrared spectroscopies Its decomposition temperature, diffraction angles vibrational modes determined. at synthesis cadmium selenide quantum dots, bismuth nanoparticles mixed copper/zinc nanocrystals. Hot-injection one-pot methods utilized synthesize these nanostructures. Their sizes, distributions, shapes, elemental compositions, crystalline structures investigated transmission electron microscopy energy analysis. Mixed nanocrystals also examined spectroscopy.
