Liquid carbon dioxide coating of CdS quantum-dots on mesoporous TiO2 film for sensitized solar cell applications
W Jang, EB Nursanto, J Kim, SJ Park, BK Min… - The Journal of …, 2012 - Elsevier
CdS quantum dots (QDs) were uniformly deposited on mesoporous TiO2 films by high-
pressure coating with liquid carbon dioxide (l-CO2) as a coating solvent. The size and
coverage of CdS QDs over the TiO2 surface were controlled by the number of l-CO2 coating
cycles applied at a fixed precursor concentration. The formation of CdS QDs on the
mesoporous TiO2 film was confirmed by scanning electron microscopy (SEM) and high-
resolution transmission electron microscopy (HR-TEM). In addition, depth profiling …
