It has been reported that the physical properties of Nanoparticles, including their optical, electrical, and thermal characteristics, can be modulated by the nanostructures that emerge from aggregate formations [1]. In this study, we utilize Quantum Dots (QDs) as nanostructures in conjunction with non-ionic surfactant Brij58(C16EO20). The induction of structure melting of Brij58 in water is achieved by mixing it with QDs, and this is subsequently emulsified using ultrasonication. The initial step involves the evaporation of the organic solvent, followed by the evaporation of water to achieve a 35 wt % (w/w) Brij58-water mixture. The analysis of QDs and QD-composites involves the use of Small Angle X-ray, Neutron Scattering (SAXS). The SAS experiment was conducted within the temperature range of 25 °C to 80 °C.
