Title: The Innovative Contributions of Robin W Munn
Introduction
Robin W Munn is a notable inventor based in Sayre, PA (US). He has made significant contributions to the field of phosphor technology, holding a total of 12 patents. His work focuses on improving the performance and efficiency of fluorescent lamps through innovative phosphor formulations.
Latest Patents
Among his latest patents is the development of an Europium-doped yttrium oxide phosphor. This invention discloses a large size Y.sub.2 O.sub.3:Eu lamp phosphor that serves as a red component for a water degradation resistant blend of fluorescent phosphors. The method involves blending yttrium oxide and europium oxide with fluxing agents, firing, and milling the fired phosphor. The resulting phosphor is sieved to achieve an average particle size greater than about 5, and a conformal coating of gamma alumina is applied through chemical vapor deposition. This results in a coated Y.sub.2 O.sub.3:Eu phosphor that includes additional phosphor components, such as a green phosphor, to create a lamp phosphor blend suitable for application as a water-based suspension.
Another significant patent involves a method of forming a partial protective coating on phosphor particles. This method aims to enhance the initial power output and maintenance of fluorescent lamps made with the phosphor. The phosphor particles are fluidized in a bed and partially enveloped by a coating precursor material. The residence time in the fluidized bed is short, allowing for only a partial coating. The coating precursor material is then reacted to form a protective layer over certain sites on the phosphor particles, which are subsequently annealed to ensure selective coverage.
