摘要:
A method of preparing a sol-gel material is described. A metal alkoxide and an organically modified Si-alkoxide having a predetermined functional group are dissolved in a first solvent and a second solvent to form a first solution and a second solution, respectively. The first solution and the second solution are then mixed and heated. As a result, the metal alkoxide reacts with the organically modified Si-alkoxide, and a functionalized sol-gel material is formed thereby. Furthermore, the solid content of the functionalized sol-gel material is increased by transferring the same into another solvent. Therefore, a thick sol-gel film is fabricated by means of the transferred functionalized sol-gel material.

Fused quartz containing europium oxide, titanium dioxide and cerium oxide has been found to be effective for absorbing UV radiation while transmitting visible light radiation. Uses for this material include lamp envelopes and shrouds for halogen-incandescent lamps and metal halide arc discharge lamps which emit both UV and visible light radiation.
