摘要：

In this work, red and green CdSe/ZnS quantum dots (QDs) as color-converting layers to combine with blue micro-LED by transfer printing for full-color display were proposed. A distributed Bragg reflector (DBR) was designed and fabricated to reflect the excess blue light to both increase the utilization of the blue light from micro-LED and improve the color purity of the red and green light from QDs. Red and green QDs arrays on glass substrate were presented by transfer printing via polydimethylsiloxane (PDMS) stamp. The red QDs transferred on the DBR as color- converting layer was then attached with the blue micro-LED, and the red QDs down-converted the blue emission from the micro-LED to the red emission. These results provided the promising potential of transfer printing QDs as color-converting layer to realize full-color micro-LED display.
