<p>A method of making a mercury-free fluorescent lamp in which a layer of phosphor particles are applied to an exterior surface of the lamp envelope, includes preparing a sol-gel precursor solution that, when dried, leaves a sol-gel residue material, such as thin film SiO 2 , that coats the phosphor particles and resists removal of the phosphor particles from the exterior surface, dipping the envelope into the sol-gel precursor solution, and, after removing the envelope from the solution, drying the sol-gel precursor solution to form a network of the sol-gel residue material on the exterior surface that meshes with the layer of phosphor particles. The sol-gel residue material attaches the phosphor particles to the exterior surface with sufficient strength so that the lamp can be handled as if the layer of phosphor particles were on the interior of the envelope.</p> |
