Improved luminescence from CdSe quantum dots with a strain-compensated shell

(author unknown)



Y. Lu, Y. Q. Zhang, and X. A. Cao

Colloidal CdSe quantum dots (QDs) with a strain-compensated ZnS/ZnCdS bilayer shell were synthesized and characterized. The core/shell/shell structure enjoys the benefits of excellent exciton confinement by the ZnS intermediate shell and strain compensation by the ZnCdS outer shell. The resulting ... [Appl. Phys.
