Abstract

Due to the Auger effect, traditional core/shell quantum dots exhibit emission intermittency, which affects the application of quantum dots on lasers. A thick shell could effectively inhibit the Auger nonradiation process, which makes the quantum dots have high optical gain. In addition, the thick shell can effectively eliminate the influence of the external environment on the excitons in the nucleus, thus greatly improving the optical and chemical stability of the quantum dots. Therefore, a number of research groups, including our research group, have conducted extensive research on thick-shell core/shell quantum dots. This chapter will review the important works of this kind of quantum dots according to the following contents.
