Abstract
A method includes obtaining a potassium hexafluorosilicate (PFS)-based powder, obtaining a fluidization material, and mixing the PFS-based powder with the fluidization material to form a PFS-based mixture. The PFS-based mixture is configured to be mixed with a resinous material to form a flowing phosphor blend configured to be placed onto a light source to form a phosphor on the light source.
Claims15
A phosphor body formed from:
- a potassium hexafluorosilicate-based powder, wherein the potassium hexafluorosilicate-based powder comprises potassium hexafluorosilicate doped with manganese;
- a fumed silica fluidization material, wherein the fumed silica fluidization material is present in an amount less than or equal to 0.1 wt % relative to a weight of the potassium hexafluorosilicate-based powder;
- and
- a resinous material.
