Electron Microscopy and Optical Characterization of Cadmium Sulphide Nanocrystals Deposited on the Patterned Surface of Diatom Biosilica
Figure 4
TEM EDX spectrum details the chemical composition of the CdS-coated frustule shown in the insert. The red dot is the spot where the chemical composition was taken. The Cu peak is an artifact of the TEM grid.
