Porous Silicon Photoluminescence Sensors of Organic Compounds

Abstrakt

The paper gives an overview of porous silicon applications in sensing of gaseous and liquid analytes. Selected chemical reaction routes for modification of as-prepared (H-terminated) porous silicon surface are described.

Relationship between surface chemical composition of porous silicon sensor elements and photoluminescence sensor response sensitivity and selectivity to organic analytes in gas and liquid phase is discussed.
