AB  - We deposited Au-Cu-Si, an Au-based thin-film metallic glass (TFMG) of  approximately 50 nm 
      thickness, as the activation layer for propagating surface plasmon resonance 
      (PSPR)-based sensors on a BK7 glass substrate to substitute the commonly used 
      gold layer. The film composition was tuned to yield the maximum Au content ( approximately 65 
      at %), while the structure remained amorphous. The results showed that the 
      Au-based TFMG could support surface plasmon resonance and gave rise to the 
      extinction in the angle-resolved reflection spectrum. Using deionized water and 
      ethyl alcohol with the refractive index difference of  approximately 0.03 as the analytes, the 
      angle shift given by Au-based TFMG was 4 degrees  compared to 5 degrees  given by the Au film. 
      Hence, Au-based TFMG is feasible to be used as the activation layer in PSPR-based 
      sensors. Compared to the Au film, Au-based TFMG has the advantages of being less 
      expensive, lacking grain boundary scattering, better adhesion to the substrate, 
      and higher resistance to scratch and corrosion because of its amorphous structure 
      with excellent mechanical properties.
