Optical element and electronic device including the same

An optical element, comprising:

• a film having a single layer structure and comprising a first host matrix and a plurality of nanowire arrays dispersed in the first host matrix, each of the nanowire arrays comprising a plurality of nanowires dispersed in the first host matrix and at least two of the plurality of nanowire arrays being arranged along a longitudinal direction of the plurality of nanowires;
• and
• a light emitting material disposed on the nanowires and dispersed in the first host matrix,
• wherein the plurality of nanowires in each of the nanowire arrays are longitudinally aligned in the nanowire array to linearly polarize at least a portion of light emitted from the light emitting material, and
• wherein the plurality of nanowire arrays is fully surrounded by the first host matrix, the first host matrix consists of a transparent and insulative polymer,
• wherein an average of lengths of the plurality of nanowires is greater than or equal to about 3 μm and less than or equal to about 500 μm,
• wherein at least one of the plurality of nanowires comprises a first metal segment having magnetism and a second metal segment capable of causing surface plasmon resonance, the second metal segment is immediately next to the first metal segment.
