文摘
- •
Structural and properties of Co2+/Cr3+: MgGa2O4 nanoparticles were characterized.
- •
The distribution of cations was studied using XPS.
- •
The inversion degree increased with increasing content of doping ions.
- •
The doping concentration has also effect on absorption and emission properties.
- •
Optical properties of nanoparticles were discussed based on the structural results.
