| titleOfInvention | Core-shell phosphor produced by heat-treating a precursor in the presence of lithium tetraborate |
| abstract | The phosphor of the invention is characterized in that same is capable of being produced by a method in which a precursor including particles having an average diameter of between 1.5 and 15 micrometers is heat-treated under a reducing atmosphere, said particles including a mineral core and a shell containing a composite phosphate of lanthanum and/or cerium, optionally doped with terbium, which covers the mineral core uniformly over a thickness greater than or equal to 300 nm, the heat treatment taking place in the presence of lithium tetraborate (Li2B4O7), as a fluxing agent, in a mass quantity of at most 0.2%, at a temperature of between 1050°C and 1150°C and for a time period of between 2 hours and 4 hours. |
