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.
