摘要：

The generation of a surface plasmon wave at a palladium interface is used in the design of an all optical hydrogen sensor. Large (> 90%) changes in reflected light intensity from the sensor element are observed when the sensor is exposed to hydrogen concentrations corresponding to percentage levels. This is a ten-fold enhancement of the reflectivity change observed in sensors using normal reflection from palladium.
