摘要：

Efficient visible photoluminescence of porous Si is observed on highly porous material, which is currently attributed to quantum confinement effects of the carrier in nanometric sized silicon wires or dots. In this work, the growth of porous silicon layer has been monitored using electrochemical impedance technique.
