Figure 2From: Functionalized silicon quantum dots by N-vinylcarbazole: synthesis and spectroscopic propertiesCharacterization of Si QDs and N-ec-Si QDs. (a) XRD pattern of the hydrogen-terminated Si QDs. (b) TEM image and HRTEM image (inset) of the N-ec-Si QDs (scale bar 20 nm, inset 2 nm). (c) Size distribution of the N-ec-Si QDs. (d) FTIR spectra of the N-ec-Si QDs and pure N-vinylcarbazole.Back to article page
