Porous silicon (PS) is a new kind of nanometer semiconductor electro-optic material with excellent properties, such as photoluminescence (PL), electroluminescence (EL) characteristics in room temperature. PS has the promising potential for application in multi-fields including electro-optic devices owing to its outstanding properties and being compatible easily with modern Si technology. The applications of PS as insulating materials, sensitive materials and sensors, illuminating materials and solar cell, optoelectronic devices and so-called materials assistantly synthesized with PS are introduced in the paper, and the prospect of PS is also discussed.
