During the past two years, many research groups have been focusing great interest on the study of properties of luminescent porous silicon (PS). In this paper, we describe the current progress in electroluminescent PS devices, various PS device structures and corresponding optoelectronic parameters, combining with our recent research in this region. The importance of electroluminescent PS devices in silicon optoelectronic integration, their potential applications in technologies and some unsolved problems are also included.
