Abstract

A method of preparing a solution for forming a doped gel monolith includes providing a first substance including a metal alkoxide. The method further includes providing a second substance including a catalyst. The method further includes providing a chemical including a dopant. The method further includes forming a solution including the dopant, said forming including mixing the first substance and the second substance together. The method further includes cooling the solution to a mixture temperature which is at or below zero degrees Celsius, wherein the solution has a significantly longer gelation time at the mixture temperature than at room temperature.
