They have shown great potential as active materials in optoelectronic applications. In the last 6&nbsp;years, their certified photovoltaic efficiencies have reached 22.1%. Compared to bulk halide perovskites, low-dimensional ones exhibited novel physical properties. The photoluminescence quantum yields of perovskite quantum dots are close to 100%. The external quantum efficiencies and current efficiencies of perovskite quantum dot light-emitting diodes have reached 8% and 43&nbsp;cd&nbsp;A<sup>−1</sup>, respectively, and their nanowire lasers show ultralow-threshold room-temperature lasing with emission tunability and ease of synthesis. Perovskite nanowire photodetectors reached a responsivity of 10&nbsp;A&nbsp;W<sup>−1</sup> and a specific normalized detectivity of the order of 10<sup>12</sup> Jones. Different from most reported reviews focusing on photovoltaic applications, we summarize the rapid progress in the study of low-dimensional perovskite materials, as well as their promising applications in optoelectronic devices. In particular, we review the wide tunability of fabrication methods and the state-of-the-art research outputs of low-dimensional perovskite optoelectronic devices. Finally, the anticipated challenges and potential for this exciting research are proposed.</p>}, number={3}, journal={Nano-Micro Letters}, author={Zhang, Jian and Yang, Xiaokun and Deng, Hui and Qiao, Keke and Farooq, Umar and Ishaq, Muhammad and Yi, Fei and Liu, Huan and Tang, Jiang and Song, Haisheng}, year={2017}, month={Mar.}, pages={36} }
