摘要：
PbSe quantum dots have attracted a great number of attentions due to their tunable bandgap in a wide range, high photoluminescence quantum yields and low-cost solution process, thus enabling them the potential as key functional materials in infrared region. However, PbSe quantum dots are sensitive to air, resulting in the decrease or even destroy of their optical properties. Overcoating of PbSe quantum dots by a suitable shell, yielding PbSe-based core/shell quantum dots, have been successfully demonstrated to be an effective strategy to improve the chemical stability and optical properties. In this mini-review paper, we summarized the progress of colloidal synthesis methods of PbSe-based core/shell quantum dots and their optoelectronic applications in photodetectors, solar cells, lasers and photocatalysis. We hope the review can attract the attention from both of the industrial and academic researchers. © 2020, Science Press. All right reserved.
