Structural images and ensemble optical properties of gNCCs. a, b, c, d TEM (transmission electron microscopy) images showing the formation of CdSe/CdS gNCCs with the CdS shell thicknesses of 5, 10, 15, and 20 MLs, respectively. e, f High-resolution TEM images of two single CdSe/CdS gNCCs. g Absorption and emission spectra of ensemble CdSe/CdS gNCCs. h Photoluminescence (PL) decay curve of ensemble CdSe/CdS gNCCs fitted with a single-exponential lifetime of 93.1 ns. The optical measurements in (g) and (h) were performed at room temperature. The scale bars used in (a–d) represent 50 nm, while those in (e) and (f) represent 5 nm
