ABSTRACT:

Visible light emission is reported from boron doped p+ type porous silicon films. These films were prepared by stain etched method. In this method KOH pallets were used in de-ionized water at 75?C for etching silicon samples. Blue and green light area observed from these porous silicon samples. The visible photoluminescence originates from direct transitions between energy levels in the quantum wells.
