Abstract: A thermophotovoltaic (TPV) system, comprises a substrate, an emitter material adhered to the substrate, and a thermophotovoltaic (TPV) cell. The emitter material is a typically a metal oxide doped nickel oxide sol-gel material, in which the metal is magnesium or zirconium, and in which the sol-gel material comprises 97-99 mol% metal oxide, and about 1-3 mol% nickel oxide dopant. Providing an emitter material as a sol-gel allows the material to be coated on to surfaces providing better adherence to the surface, and also provides excellent heat stability. A sol-gel material is also described.

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.
