Multi-band emission in a wide wavelength range from tin oxide/Au nanocomposites grown on porous anodic alumina substrate (AAO)

- Tin oxide nanostructures of various morphology covered by Au NPs were synthesized.
- Photoluminescence (PL) maps of the nanostructures were acquired.
- Various morphology induced different surface composition of tin oxide nanostructures.
- The luminescence dependence on tin oxide surface composition was found.
- Influence of Au nanoparticles on the defect-related optical emission was examined.
