An optically transparent graphene-based wire-grid polarizer for operating at microwave frequencies (X band) has a glass substrate having multiple strips or layers of SOCl.sub.2 doped graphene. The strips are separated by portions of the glass substrate such that the strips are arranged in parallel. The SOCl.sub.2 doped graphene strips have a quasi-metallic quality allowing for the transmission of an electric field with horizontal polarization in the horizontal direction while reflecting the vertical portion of the electric field.

The present invention provides a method for manufacturing a quantum dot color filter, which uses a printing mold to pick up quantum dots and printing the quantum dots into a partially cured photoresist layer and then separates the quantum dots and the printing mold, followed by irradiation of UV light to completely cure the photoresist layer so that the quantum dots may uniformly distributed in the photoresist layer. This simplifies the process of transferring a quantum dot layer and reduces cost; requires no process of forming a sacrifice layer and no step of dissolving the sacrifice layer to prevent damage to the quantum dot layer; allows the quantum dots to be uniformly distributed in the photoresist layer to thereby improve the utilization of the quantum dots; and allows a quantum dot color filter so manufactured to be used with white backlighting or blue backlighting for achieving displaying of three primary colors of red, green, and blue.
