Multiphoton excitation of luminescence from porous silicon

Not Accessible

Your library or personal account may give you access

Abstract

Porous Si is known to be a potential material that could lead to novel, Si-based luminescent devices. Efficient visible photoluminescence by UV irradiation of porous Si can be readily observed. Direct carreir excitation followed by carrier relaxation and finally electron-hole recombination is responsible for the observed luminescence. The luminescent wavelength depends on the effective cluster size of the porous Si.
