| Description |
Thioglycolic acid capped cadmium selenide (CdSe) quantum dots have been prepared by chemical synthesis method. HR-TEM and SAED characterization confirm the formation of CdSe quantum dots with approximate particle size of 3.8 nm which is also comparable to the crystallite size as determined from the XRD analysis. This II-VI semiconductor quantum dot is introduced in a positive dielectric anisotropic liquid crystal host and then injected into a twisted nematic liquid crystal cell where the dots agglomerates and sports ordered arrays. Effect of the application of dc voltage on the composite system is also observed with an optical polarizing microscope.
