Abstract:

The effect of oxygen and hydrogen on the photoluminescence intensity of porous silicon was examined. The results indicate that the presence of oxygen is necessary for visible light emission. In contrast, high hydrogen passivation is unfavorable for visible light emission.

Key words: Porous silicon, photoluminescence intensity, Hydrogen passivation
