Figure 2From: CuInS2 quantum dot-sensitized TiO2 nanorod array photoelectrodes: synthesis and performance optimizationTEM (a) and HRTEM (b) images of CuInS 2 quantum dots. The CuInS2 quantum dots are deposited onto a TiO2 nanorod; the SILAR cycle number for CuInS2 deposition was 7.Back to article page
