Particular attention in SONAR project will be devoted to the outreach within the network, i.e. publications on scientific journals, conference proceedings and other types of disseminations.

New synthesis protocols for various dSNCs

Control over the dSNC size, shape, crystallinity and the distribution of dopants and defects, as well as surface traps to impact the plasmonic response. Different levels of vacancy doping guaranteed by coating of the dSCN by a shell or the incorporation in appropriate film structures to prevent further oxidation or reduction.
