Could you please specify your question?

A linear polarization of the ground state exciton luminescence may be due to anisotropic electron hole exchange.

If I add a small concentration of quantum dots (size between 2.5 to 5 nm) in a ferroelectric liquid crystal (FLC), what are the possible reason if the spontaneous polarization of FLC do not change after addition of QDs?

I fear I am not able to help you with your issue.

Maybe you could describe the mechanism that would normally lead to a change in the spontaneous polarization of your ferroelectric liquid by adding low concentrations of QDs.

I would guess that adding anything that alters your liquids concentration will usually lead to a change in the spontaneous polarization, right? If this is not the case the QDs are inactiv to your process meaning there is no effect from tham. Why? How large are your FLCs? Maybe the QDs fit in between the crystals.

Kind regards,

Arne

Thanks dear Arne for your suggestion.

Dear Dharmendra..

Did you find any change in physical parameters in liquid crystals by adding QDs. At what %ge and which kind (calamitic , bend, disc, +ve or negative anisotropy) of liquid crystals.

Dear Venkata,

yes, i find some change in FLC parameters with the addition of QDs, especially in commercially available FLC mixtures..but things are totally different with single component FLC. concentration should be small to avoid the formation of aggregates.
