发光多孔硅的化学传感特征

Chemical Sensing Properties of Luminescent Porous Silicon

发光多孔硅是一种新型的光电器件材料。其荧光的猝灭或增敏，以及其电学特性（电容、电导等）的变化可作为化学传感信息用于化学传感技术。本文评述了自发光多孔硅首次报道以来在化学传感领域的应用研究进展。

Room temperature luminescent porous silicon is a new type of material for optoelectronic devices. The quenching or enhancement of visible photoluminescence and the changes of electric properties from porous silicon, as chemical sensing information, may be used in the chemical sensing technology. This review summarizes the researches on porous silicon for the chemical sensing purpose from the first report of luminescent porous silicon to 1995.,
