Latest Patents

One of his latest patents is titled "Production of substantially monodisperse phosphor particles." This invention relates to a method for producing activated, substantially monodisperse, phosphorescent particles. The method involves suspending substantially monodisperse, phosphor-precursor particles in a fluidizing gas and introducing a reactive gas to contact the suspended particles. By heating these particles to a reaction temperature, unactivated phosphorescent particles are formed. In another embodiment, the phosphor-precursor particles may decompose to create the unactivated phosphor particles. The unactivated phosphorescent particles are then activated by heating them to an activation temperature, resulting in activated, substantially monodisperse, phosphorescent particles.

Another significant patent is for a "Fluidized bed reactor to deposit a material on a surface by chemical vapor deposition." This reactor is designed for the chemical vapor deposition of a coating on a substrate surface. It enables high rates of deposition and a highly homogeneous coating by modifying the boundary layer formed between the gasified reactive gas stream and the substrate. The design minimizes the boundary layer through an exhaust outlet placed near the center of the substrate surface and/or a gas inlet that injects a tangential stream of gas, creating a swirling radial flow of reactive gas.
