Latest Patents

Garreth Wakefield holds a patent for "Ternary oxide phosphor particles." This invention involves the preparation of phosphor compositions by treating metal oxides or mixed-metal oxides with refractory metals. The resulting cathodoluminescent phosphors are stimulatable by electrons of very low energy. The phosphors consist of a mixed metal oxide and a dopant, which may include rare earth elements or other substances. A notable embodiment of this invention is a blue-light-emitting phosphor based on ZnO treated with Ta O or Ta, characterized by specific CIE 1931 chromaticity values. This technology is particularly useful in the fabrication of displays, where the phosphor can be formed in situ during the manufacturing process.
