A. Mews et al., PREPARATION, CHARACTERIZATION, AND PHOTOPHYSICS OF THE QUANTUM-DOT QUANTUM-WELL SYSTEM CDS HGS/CDS/, Journal of physical chemistry, 98(3), 1994, pp. 934-941
The synthetic procedure, the characterization, and some photophysical
properties of a quantum dot quantum well (QDQW) system are described i
n detail. The novel structures prepared via wet chemical methods consi
st of a core of size-quantized CdS and a well of 1-3 monolayers of HgS
capped by 1-5 monolayers of CdS acting as the outermost shell. Additi
onally, theoretical calculations based on the effective mass approxima
tion appropriate to describe the 1s-1s electronic transition of the co
mposite particles are presented.
