Facile fabrication of large-area and uniform silica nanospheres monolayer for efficient surface-enhanced Raman scattering

- Large-area monolayers were fabricated by Langmuir-Blodgett (LB) assembly and sputter coating process.
- The diameter of nanospheres and the surface pressures have an effect on ordered arrangement monolayers.
- Study of the uniformity enhancement of the Raman signal across the entire surface.
