Synthesis and inkjet printing of aqueous ZnS:Mn nanoparticles

► Highly monodisperse ZnS:Mn nanoparticles were prepared in aqueous solution. ► ZnS:Mn incorporated into a fluid with suitable properties for inkjet printing. ► Photoluminescence was bright on impermeable substrates but quenched on paper. ► Film smoothness was compromised by high solids loading, and high viscosity of ink.
