Abstract
English (OpenAlex)
In this work, cadmium telluride core type quantum dots (CdTe QDs) were dispersed in 4-pentyl-4′-cyanobiphenyl (5CB) nematic liquid crystal (LC) with a concentration of 0.05 % wt/wt; and their electrical and dielectric properties were investigated by using admittance measurements in the frequency range of 100 Hz - 10 MHz. In order to determine the effects of CdTe QDs in 5CB nematic LC, dielectric anisotropy (∆ε), crossover frequency (fcrossover), critical frequency (fcritical), real and imaginary parts of permittivity (ε' and ε") of neat LC and CdTe QDs dispersed LC composites were obtained using the experimental data. Moreover, threshold voltage (Vth), splay elastic constant (K11) were also calculated. It was found that Vth and K11 of QDs dispersed LC are significantly decreased due to the existence of CdTe QDs.
