A method of manufacturing a composition with improved quantum yield, containing at least these steps: a/ manufacturing a mixture by at least these steps: 1/ providing a semiconducting light emitting nanoparticle, 2/ adding a macromolecular compound comprising at least an anchoring group; 3/ adding an organic additive, and b/ subjecting the mixture from step a/ to irradiation with light of a wavelength in the range of 300 to 600 nm having an intensity in the range of 0.025 to 1 W/cmto obtain the composition; wherein the organic additive is defined by formula (Ia): M-(X—Y), wherein M is a divalent metal ion, X is a hydrocarbon chain, and Y is a functional group.

Composition comprising semiconducting light emitting nanoparticles

Suggested is a semiconductor nano-sized light emitting material having a ligand.

Semiconducting light emitting material

The present invention relates to a method for preparing a nanosized light emitting semiconductor material.

Semiconductor light emitting nanoparticle

The present invention provides an optically active structure and the use thereof in a backlight unit. The optically active structure comprises a plurality of optically active particles configured to emit light of one or more predetermined wavelength range in response to pumping energy, and a plurality of light scattering elements. The plurality of light scattering elements comprises optically transparent void regions, such as void regions surrounding filler particles.

Emitting film with improved light-out coupling

A polarized light source configured for use in display device and backlight unit is described. The polarized light source comprising: at least one optically active structure comprising a plurality of nanorods configured to emit light of one or more wavelengths in response to exciting pumping field, said plurality of nanorods comprising nanorods aligned with a predetermined alignment axis so as to produce a desired polarization direction of the emitted light; and a light directing assembly comprising one or more optical elements in optical path of light emitted from the light emitting structure, said light directing assembly being configured to enhance output of the emitted light from the emitting structure while substantially maintaining the polarization of the emitted light passing therethrough. Preferably, layers associated with the polarized light source are aligned with parallel principal axes.
