我们报道了将微图案聚芴共轭聚合物集成到氮化镓基紫外微像素发光二极管阵列(micro- led)上。64× 64元矩阵可寻址AlInGaN器件的像素尺寸为直径20微米,间距为50微米,发射波长为368nm。每个阵列都覆盖有2.5微米厚的光固化深紫外透明聚合物和30纳米厚的聚芴薄膜。这种聚合物双层随后被图案化成直径28微米的圆盘阵列,与微型led阵列的像素对齐。这些模式可编程的有机/无机电致发光微阵列实现了聚合物下转换可见发射。
We report the integration of micro-patterned polyfluorene conjugated polymers onto GaN-based ultraviolet (UV) micro-pixellated light-emitting diode arrays (micro-LEDs). The 64× 64 element matrix-addressable AlInGaN devices have a pixel size of 20 µm diameter on a 50 µm pitch, emitting at 368 nm. Each array is covered with a 2.5 µm thick photo-curable deep-UV-transparent polymer and a 30 nm thick polyfluorene film. This polymer bi-layer is subsequently patterned into an array of 28 µm diameter discs aligned with the pixels of the micro-LED array. Polymer down-converted visible emission from these pattern-programmable organic/inorganic electroluminescent micro-arrays is achieved.
