TEM analysis of CdSe/ZnS Core/Shell "EviDots" (Evident Technologies) deposited on the surface of carbon-coated copper grids. Panels (A) and (B) exemplify the results obtained for ED-C11-TOL-0620 "EviDots". TEM images were used to determine the size of the quantum dots. Panel (C) illustrates power spectral density function (PSD) corresponding to image on panel (B). The corresponding radial correlation function (D) allows estimating the average diameter of the particle (5.05 nm).
