Tailoring magnetic and photoluminescence properties in ZnS/ZnO core/shell nanostructures through Cr doping

- Formation of hexagonal ZnO shell on cubic ZnS nanoparticles in alkaline aqueous solution at room temperature.
- Successful doping of Cr in both core ZnS and shell ZnO by room temperature wet chemistry.
- Tailoring of different core/shell architecture to tune luminescence and magnetic properties.
- Spin pinning at interface of core/shell magnetic regions lead to spin alignment and ferromagnetism in ZnS:Cr/ZnO:Cr core shell nanoparticles.
