Özet
In this work, electrical and dielectric properties of CdSeS/ZnS quantum dots (QDs) doped Polymer/Liquid Crystal composite structures (PMMA/LC) were investigated by using Dielectric Spectroscopy Technique in the frequency range of 100 Hz-10 MHz at room temperature. In order to determine the effect of quantum dot concentrations, PMMA/LC composites structure was dispersed with 0.5, 1 and 1.5 wt% CdSeS/ZnS QDs. Hence some considerable physical parameters such as dielectric constant (epsilon ' and epsilon ''), dielectric anisotropy (Delta epsilon '), relaxation frequency (f(R)), relaxation time (tau) as a function of frequency were obtained depend on QDs concentrations. Results show that QDs contribution have occurred significant changes in dielectric properties of investigated samples which can be used in PMMA/LC based device applications.
