Abstract
Chapter 2. Novel photoluminescent distributed Bragg reflector porous silicon exhibiting reflection optical properties were developed and used as chemical sensors. Adsorption and desorption characteristics of gradient Rugate-structured porous silicon (PSi) were investigated under the exposure of organic vapors. Rugate PSi samples were prepared by an electrochemical etch of p++-type silicon under the illumination with a 300 W tungsten filament bulb for the duration of etch. The etching solution consisted of a 3:1 volume mixture of aqueous 48% hydrofluoric acid and absolute ethanol. reflectivity were measured under the exposure of organic vapors. The shift of reflection band to the longer wavelength under the exposure of vatious organic vapors was obtained. The detection of volatile organic compounds (VOCs) using the gradient Rugate PSi had been acheved.
