Abstract Concentration of Si-H₂ bond in porous silicon layer (PSL) affects its photolu-minescence (PL) intensity and peak wavelength PL emission characters of PSL associate with not only its micro-structure, but also the Si-H₂ band. So a stabilization of the emission intensity and the peak wavelength can be achieved by proper photochemical processing. A stable effective PL emission at wavelength as short as 570nm can be observed on PSL made by anodization method.
