(a) and (b) show the TEM images of red emitting core/shell CdSe/ZnS NC solid films ( in ) with the scale bars of 20 and 5 nm, respectively.
(a) Absorbance and (b) photoluminescence of closely packed red emitting CdSe/ZnS core/shell NC solid films parametrized with respect to the number of NCs (0.4, 0.8, 1.6, and 2.4 nmol) compared to those in solution.
(a) Spectrally resolved relative QE and (b) relative photon conversion efficiency of red emitting CdSe/ZnS core/shell NC films with the integrated NC amounts of 0.4, 0.8, 1.6, and 2.4 nmol at the excitation wavelengths of 290, 395, 445, 493, and 544 nm along with the average of relative QE and relative photon conversion efficiency in the insets of (a) and (b), respectively. These relative efficiency levels are normalized to better present the relative change over the optical wavelength.
(a) Spectral time-resolved emission spectroscopy in the spectral emission range of 610–660 nm (with a 10 nm spectral spacing) of (a) in-solution NCs and in-film NCs with the amounts of (b) 0.4 and (c) 2.4 nmol.
