The photoluminescence (PL) properties of "porous silicon" prepared by spark erosion and of amorphous silicon carbon alloys. amorphous silicon carbon oxygen alloys and hydrogenated amorphous carbon prepared by CVD methods from liquid precursors are measured. Ellicient blue-green PL is measured as a function of temperature up to 800 K. Optical absorption data in the high energy range (UV) are obtained from transmission measurements. Very low absorption coellicients in the visible spectral range are determined in light-guiding thin film structures which are grown as a three-layer sandwich on a silicon substrate.
