Abstract
A chemical sensor for detecting organic or inorganic target vapors and comprising a silicon member having a silicon surface with semiconductor pores therein, at least one luminescent sensory material entrapped in the semiconductor pores. The luminescent spectral material is exposed to the target vapors, wherein an excitation of the at least one luminescent sensory material results in a luminescent spectral response due to emission interference. The change in the luminescent spectral response is measured during this exposure.
