Fig. 3From: Balanced Dipole Effects on Interfacial Engineering for Polymer/TiO2 Array Hybrid Solar CellsTEM (a, c) and HRTEM (b, d) images of TiO2-NRA (a, b) and TiO2-NRA@TiO2-QDs. The images of TiO2-NRA@TiO2-QDs (c, d) were processed with pseudocolor to distinguish them from TiO2-NRA (a, b). The HRTEM image (d) was taken from the white frame on the corresponding TEM images (c)Back to article page
