Embodiments of a population of buffered barrier layer coated nanostructures and a method of making the nanostructures are described. Each of the buffered barrier layer coated nanostructures includes a nanostructure, an optically transparent buffer layer disposed on the nanostructure, and an optically transparent buffered barrier layer disposed on the buffer layer. The buffered barrier layer is configured to provide a spacing between adjacent nanostructures in the population of buffered barrier layer coated nanostructures to reduce aggregation of the adjacent nanostructures. The method for making the nanostructures includes forming a solution of reverse micro-micelles using surfactants, incorporating nanostructures into the reverse micro-micelles, and incorporating a buffer agent into the reverse micro-micelles. The method further includes individually coating the nanostructures with a buffered barrier layer and isolating the buffered barrier layer coated nanostructures with the surfactants of the reverse micro-micelles disposed on the barrier layer.

The present invention provides a method for manufacturing a quantum dot polarization plate. The method for manufacturing a quantum dot polarization plate according to the present invention forms a quantum dot layer and a polarization layer separately on different bases to respectively make a quantum dot film and a polarization film and then bonds the quantum dot film and the polarization film together to form a quantum dot polarization plate. The quantum dot polarization plate is not made through successive formations of films on the same base so that the quantum dot layer of the quantum dot polarization plate can be manufactured through a high-temperature process or a low-temperature process, thereby expanding the range of material section and manufacture for quantum dots. The quantum dot polarization plate manufactured with such process helps increase color gamut coverage of the display panel, but does not cause elimination of light polarization.
