摘要：
Three-photon pumped stimulated emission and coherent random lasing from colloidal CdSe/CdS/ZnS core-multishell quantum dots are achieved for the first time. These results can offer new possibilities in biology and photonics, as well as at their intersection of biophotonics. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
