Abstract
A copper dopant delivery powder comprising a fused silica powder and a Cu2S powder. A method of making the copper dopant delivery powder. A method of making a copper-doped glass comprising placing a target glass in a container, packing a composite SiO.CuS dopant powder around the target glass and heating the container and SiO.CuS dopant powder to a temperature of between 800° C. and 1150° C. A copper-doped glass comprising a glass comprising copper-doping wherein the copper-doped glass was formed by covering the glass with a fused silica powder and a Cu2S powder, wherein the fused silica powder and the Cu2S powder are mixed in varying ratios of Cu2S to silica represented by the formula (SiO2)(1-x)(Cu2S)x and heating to a temperature of between 800° C. and 1150° C.
