Summary

Introduction

Colloidal quantum dots (QDs) have gained enormous success in optoelectronics, photovoltaics [1,2,3] and biomedical [4] applications. Several approaches to preparation of these fluorescent nanomaterials with a quantum yield close to 100% have been advanced in the past decade. One of the most prospective approach to 100%-emitting, non-blinking QDs with narrow emission band has been developed by Chen et al [5]. The key feature of these QDs is their thick CdS shell, which allows sufficient screening of luminescent CdSe cores from the environment. Such QDs are not desirable from the viewpoint of biomedical applications, since they have a relatively large physical
