Abstract
Titanium dioxide (TiO2) nanoparticles were prepared using a polystyrene‐block‐polyethyleneoxide copolymer as a template. As a preliminary study whether polydimethylsiloxane (PDMS) is a suitable polymeric replacement for barrier layers, PDMS was spin coated over the TiO2 nanoparticles and subsequently etched by oxygen plasma. The surface characteristics of the particles were investigated using Scanning Electron Microscopy and photoluminescence (PL). The PL measurements indicated the formation of exciton traps close to the particle surface after plasma treatment. The stability of the TiO2 nanoparticles upon sealing with PDMS followed by etching of the polymer overcoating was confirmed with microbeam grazing incidence small angle X‐ray scattering measurements.
