dc.description.abstractHybrid polymer structures formed with semiconductor quantum dots that are doped into the polymer matrix and whose optical properties can be adjusted have attracted attention with their high usage potential in electronic applications in recent years. In this study, three types of Cd-based QD (CdX (X=Se, Te, SeTe)) were used to strengthen the poly (vinyl alcohol) (PVA) matrix and increase its optical properties. Optical, conductivity and thermal characterizations ofPVA/3 different Cd-based QDs CdSe QD-PVA nanocomposites structures were evaluated comparatively. With the addition of QDs, it was observed that the PVA / QDs nanocomposites structure exhibits fluorescence properties. Hybridization structures in PVA/QDs nanocomposites structures were illuminated by FT-IR spectrum. In addition, it was determined that the thermal stability of hybrid polymer structures increased between 7-9% and the melting point of PVA/QDs hybrid polymers increased by 5-7 degrees C which was analyzed by DSC. The highest thermal stability and melting point increases were observed in PVA/CdSeTe QDs hybrid structures. With the addition of CdSe QDs and CdTe QDs into the PVA matrix, the conductivity value of the hybrid polymer structure increased 100 times, while the addition of CdSeTe QDs increased the conductivity by 1000 times. Similarly, in dielectric constant and dielectric loss tests, it was determined that PVA/ CdSeTe QDs hybrid polymer structures are more successful than both types due to the synergic effect.en_US
