Physical properties of liquid crystals doped with CsPbBr₃ quantum dots

Concentration-dependent dielectric and electro-optical properties of composites based on nematic liquid crystals and CdS:Mn quantum dots

“…14 Various research groups have used quantum dots to improve the optical, dielectric and spectroscopic properties of liquid crystals (LCs). [15][16][17][18][19][20] The implementation of QDs into a liquid crystal matrix leads to a decrease in the Fredericks threshold voltage, a change in dielectric and optical anisotropy, a strong quenching of LC luminescence, an accelerated response and the appearance of new relaxation modes. [21][22][23][24][25] Recent studies have reported the use of graphene quantum dots to create polyamide layers that provide both strict homeotropic alignment of the liquid crystals and ultrafast switching of the liquid crystals in an electro-optical cell.…”
