Abstract
Thermally treated porous silicon shows blue photoluminescence (400–520 nm) excited by a He‐Cd laser (320 nm) at room temperature. Stable and uniform Schottky blue light emitting diodes have been fabricated from thermally treated porous silicon in this work. The emission of blue light may be explained by the wide optical energy band gap attributed to the quantum wire effect.Keywords
