Extract

It has recently been demonstrated that highly resolved images can be produced by photochemical deposition of metal oxides in porous Vycor glass. This process has potential applications to the development of integrated optics in glass since it enables one to deposit in the same material refractive index patterns of optically and electro-magnetically active adsorbates. In order to learn in more detail about the interaction of the metal oxides with the glass, we impregnated porous Vycor glass (PVC) with tin or iron oxides and analyzed the samples with electron microscopy, x-ray microprobe analysis, and small angle x-ray scattering (SAXS). The results indicate that even though both oxides produce images of comparable resolution (approx 1μ), the interaction with the glass surface and particulate distribution is different for the two oxides. In particular, the Sn oxide appears to chemically modify the glass surface and prevents its consolidation.
