摘要：

The composition and size of optically active CdxZn1-xSe/ZnSe quantum dots are estimated with a previously developed method. The results are then compared with those obtained for CdxZn1-xSe/Zn0.97Be0.03Se QDs. We show that introducing Be into the barrier material enhances both Cd composition and quantum size effect of optically active quantum dots. (c) 2005 Elsevier Ltd. All rights reserved.
