Abstract

A composition for holographic applications, a process for making the composition and applications thereof. The process comprises gelation of a colloidal sol to yield a gel, wherein a cross-linker (e.g. an amine) and a photoinitiator are combined with the colloidal sol before or during gelation. The colloidal sol comprises a hydrolysed mixture of water; an organosilane; and an organometallic complex, the organometallic complex comprising a metal chelated by one or more ligands. The process may additionally comprise drying the colloidal sol or gel to form a xerogel.
