Abstract: The present invention provides methods for making polymerizable monomer compositions comprising purifying a (b) monomer mixture of (i) one or more monomers having at least two polymerizable vinyl groups and (ii) one or more monomers having a single polymerizable vinyl group as part of a (meth)acrylate ester group by any one or more of treating the monomer mixture in an activated porous alumina or silica column, sieve drying the monomer mixture in a vacuum followed by drying over dried molecular sieves having average pore sizes of from 2 to 20 Angstroms, freeze-pump-thaw (FPT) treating by freezing the monomer mixture in a vessel or container to a temperature below −75° C., degassing the monomer mixture by application of vacuum in the range of 102 to 10−2 Pa, sealing the vessel or container under vacuum, and thawing the composition to room temperature; and, combining in an inert gas atmosphere the resulting monomer mixture (b) with a composition (a) of quantum dots in dry form or organic solvent solution.

Abstract: Disclosed herein is a semiconducting nanoparticle comprising a one-dimensional semiconducting nanoparticle having a first end and a second end; where the second end is opposed to the first end; and two first endcaps, one of which contacts the first end and the other of which contacts the second end respectively of the one-dimensional semiconducting nanoparticle; where the first endcap that contacts the first end comprises a first semiconductor and where the first endcap extends from the first end of the one-dimensional semiconducting nanoparticle to form a first nanocrystal heterojunction; where the first endcap that contacts the second end comprises a second semiconductor; where the first endcap extends from the second end of the one-dimensional semiconducting nanoparticle to form a second nanocrystal heterojunction; and where the first semiconductor and the second semiconductor are chemically different from each other.
