Surface plasmon detection of surface contamination of metallic film surfaces
- Zhang, F. S.; Macleod, H. A.; Parks, R. E.; et. al.
Previous studies of metallic mirror surfaces using surface-plasmon resonance (SPR) showed contamination present after 3M and Universal strippable coatings were applied and removed. In this paper, we examine contamination by moisture and 3M-coating residue, and methods to reduce this contamination using ultrasonic cleaning in acetone and isopropyl alcohol. We also discuss the sensitivity of the silver film surface to roughening during ultrasonic cleaning.
