ABSTRACT
During porous etching of GaP, electroluminescence ranging from the ultraviolet to the near-infrared is generated at the interface of the porous and the nonporous layer. This is used to measure the wavelength-dependent transmission of light through porous layers in a wide thickness range. Two types of porous structures, characterized by different pore sizes, were studied. The transmission of the emitted light gives valuable information about wavelength-dependent diffusion of light through porous GaP.
