1. A method for detecting the presence of a gas in an ambient atmosphere comprising the steps of:
- transmitting electromagnetic radiation through a multiple quantum well structure and a thin mesh of a transition metal formed thereon;
exposing said mesh to an ambient atmosphere containing a gas to be detected;
monitoring detecting the presence of a gas by electromagnetic radiation transmitted through sa multiple quantum well structure and said thin mesh for a change.
