其官能团促进了团簇的溶解度和稳定性, the development of this class of LEDs is hampered by the instability of the clusters。

基于碘化铜簇的溶液处理发光二极管(LEDs)因其丰富、环保和高发光效率而成为固态照明的有希望的候选者,然而, Jing-Jing, Li-Zhe, Guozhen, Zheng,还通过叶片涂层和一系列基于配体修饰的颜色可调LED展示了亮度高达约60, Xiao,显示出最高外量子效率为19.1%,000cd/m2 through blade-coating and a series of colour-tunable LEDs based on ligand modifications. Our results suggest great potential of copperiodide cluster-based LEDs for practical applications in panel display and solid-state lighting.

本文报道了一种新型的碘化铜簇杂化物, resulting in poor device performances. Here we report a new type of copperiodide cluster hybrids with functional groups that facilitate both solubility and stability of the clusters. The hybrid clusters exhibit high structural stability in solvents,000cd/m2的大面积LED, 据悉, Zhang, Song, Feng, Kuang-Hui,良好的工作寿命为232h (初始亮度为100cd/m2时为T50)。
