摘要
来自浙江大学和剑桥大学的研究人员利用光刻技术制造出了这些像素，这些像素通过局部电接触来定义活跃像素，并防止边界处的非辐射损耗。这导致像素的外部量子效率在像素长度低于3.5 μm时约为20%，在更小的像素尺寸时为5%至10%。该团队创造了钙钛矿微型led，可以发出近红外、红色、绿色和天蓝色的光。绿色像素的外量子效率大于10%，峰值亮度超过300,000 cd m−2，最大寿命约为40小时。他们还建立了一个基于商业薄膜晶体管阵列的微型led显示器原型。
The researchers — who are based at Zhejiang University and the University of Cambridge — fabricated the pixels using lithography techniques to create localized electrical contacts that define the active pixels and prevent non-radiative losses at the boundaries. This results in pixels with external quantum efficiencies of around 20% for pixel lengths down to 3.5 μm and between 5% and 10% for smaller pixel sizes.
The team created perovskite micro-LEDs that could emit near-infrared, red, green and sky-blue light. The green pixels, with an external quantum efficiency larger than 10%, had a peak luminance of more than 300,000 cd m−2 and a maximum lifetime of around 40 hours. They also built a micro-LED display prototype based on a commercial thin-film transistor array.
