Abstract
The photoluminescence(PL) of porous Si that has been hydrogenated in boiling water has been investigated. The PL intensity is observed to increase with a concurrent shift of the spectral peak to shorter wavelengths. These effects can be explained in terms of size effects in the microstructures of porous Si. The spectral changes after annealing and after rehydrogenation are similar to the behavior of a‐Si:H. We conclude that hydrogen plays an important role in the luminescence of porous Si.This publication has 13 references indexed in Scilit:
