Stable colloidal dispersion of luminescing silicon nanoparticles for inkjet printing

Gupta A., Khalil A.S.G., Winterer M., Wiggers H., Universität Duisburg-Essen, DE

In this study, we synthesized Si-NPs with mean diameter about 4.2 nm in a microwave plasma reactor. In order to disperse these Si-NPs in organic solvent, the surface of freshly etched Si-NPs was modified with [...]

Ink-jet printed ZnO Nanoparticle Thin Films for Sensing Applications

Hartner S., Khalil A.S.G., Ali M., Winterer M., Wiggers H., University Duisburg-Essen, DE

Stable aqueous dispersions of ZnO NPs are successfully prepared with a new polymeric stabilizer. The dispersions are stable for at least 2 months without any observable sedimentation. The zeta potential and the size of the [...]
