• Surface plasmon
• Diamond-like carbon
• Nanocrystallites
• Gas-sensing

Diamond-like carbon films with embedded copper nanocrystallites were deposited on SnO2-coated glass substrates by using electrochemical technique. These composite films were subjected to sensing H2S gas. Change in the intensity of the characteristic surface plasmon resonance (SPR) peak was recorded with time, and it was observed that the SPR peak disappeared within a short time after exposure to hydrogen sulphide gas. Sensing mechanism was critically analysed.
