The shift of this threshold in comparison to structures evaporated and consequently annealed is probably caused by the surface diffusion in combination with local gold melting. The thermal annealing, on the contrary, leads to the creation of relatively large ‘spherolytic and hummock-like’ structures in the gold layer. The globular structure is strongly amplified by the thermal annealing probably due to local surface melting of gold nanoparticles during the process. The optical properties and appearance of peak
of plasmon resonance for different thicknesses of Au structures are strongly influenced by prior glass heating.
