摘要： The disclosure concerns compositions and methods to improve remote phosphor optical properties in polycarbonate. One method includes combining a phosphor component and a polycarbonate component to form a phosphor-polycarbonate composition; and at a fixed phosphor concentration, combining the phosphor-polycarbonate composition with a diffusing agent comprising polytetrafluoroethylene (PTFE), wherein the diffusing agent diffuses light, and wherein the phosphor-polycarbonate composition exhibits an increase in chromaticity coordinate (CIEx) as determined by CIE 1931 or increase in CIE 1976 (u',v') of at least about 5% relative to a substantially similar reference composition in the absence of PTFE. Also described are methods to increase yield and reduce product accumulation of an extruded thermoplastic polycarbonate composition through the mixing of PTFE with a phosphor-polycarbonate (PCP)to form a PCP-PTFE component as well as a method forming a phosphor-polycarbonate master batch (PPCMB) composition, and during extrusion, adding PTFE to the PPCMB composition to form a PPCMB-PTFE composition.

摘要： A multi-layer film may comprise a first quantum dot layer comprising a first polymer matrix and a plurality of first quantum dots disposed therein. A second quantum dot layer may be disposed adjacent the first quantum dot layer and may comprise a second polymer matrix and a plurality of second quantum dots disposed therein. The plurality of first quantum dots may be spaced from each other within the first polymer matrix to define gaps there between. The plurality of first quantum dots may emit a first secondary light upon excitation by light produced from a light source. At least a portion of the plurality of second quantum dots may be positioned to align with the gaps defined in the first polymer matrix along an axis that is orthogonal to the first quantum dot layer and the second quantum dot layer.
