   Abstract:
   A method for the preparation of thin gold film on glass slides has been described. When thin films of methylcellulose containing chloroauric acid are irradiated in a photoreactor under UV light, they produce a clear gold mirror made of aggregated gold particles stabilized by methylcellulose. The metal film can be used as a practical substrate for surface-enhanced Raman scattering. The substrate is stable and easy to prepare.
