Figure 3From: Rational design of the gram-scale synthesis of nearly monodisperse semiconductor nanocrystals TEM images and spectra of the final, purified samples. (a, b, c) TEM images of the obtained 4.0-, 5.0-, and 6.7-nm CdSe nanocrystals (from left to right). (d) Corresponding UV-vis absorption spectra; (e) normalized PL spectra (excitation wavelength, 450 nm).Back to article page
