Tunable optical properties of hybrid inorganic-organic [(TiO2)m(Ti-O-C6H4-O-)k]n superlattice thin films

16 December, 2014 - 09:54

Dalton Trans., 2015, 44,591-597
DOI: 10.1039/C4DT02550D, PaperJanne-Petteri Niemela, Maarit Karppinen
The ALD/MLD technique can be used to fabricate superlattice structures with single-molecular organic layers between thicker TiO2 layers. The organic layers enable systematic control of the optical properties of TiO2 thin films, a fact that could be of substantial interest for photocatalysis and solar cell applications.
