The Influence of Preparation Conditions on the Photoluminescence of Porous Silicon Material

under the different preparation conditions, the photoluminescence characteristic of porous silicon was different. This was a primary reason that caused many researches had the difference. This article used electrochemistry method to prepare porous silicon. The main research was that the influence of preparation conditions on the porous silicon's photoluminescence characteristic, the preparation conditions included the density of electrolyte、current density、corrosion time、lying time and so on。
