Figure 2From: Formation of PbSe/CdSe Core/Shell Nanocrystals for Stable Near-Infrared High Photoluminescence EmissionAbsorption (a) and photoluminescence (b) spectra recorded during CdSe shell growth. A consistent red shift of the peak wavelength (11, 10, 11 nm) was observed when one to three monolayers of CdSe shells grown on 4.8 nm PbSe coresBack to article page
