COLLOID FORMATION IN COPPER-IMPLANTED FUSED-SILICA AND SILICATE-GLASSES

[摘要] Copper implantations (90 keV, 5 x 10(16) ionS/CM2) were made into fused silica, borosilicate glasses and soda-lime glass. The copper distribution has been found to vary according to glass type. The optical absorption band characteristic of the implanted metal optical properties was observed only for copper-implanted fused silica. The absorption for all the other samples was either not observable or was negligibly small, however very small metallic particles are present also in the soda-lime glass. A subsequent nitrogen implantation (100 keV, 1.5 x 10(17) ions/cm2) completely eliminated the copper-colloid induced absorption in the copper-implanted fused silica, while it facilitated the formation of copper-colloids.into the soda-lime glass.
