| titleOfInvention | Core-shell phosphor produced by heat-treating a precursor in the presence of lithium tetraborate |
| abstract | The luminophore of the invention is characterized in that it is obtainable by a process in which a precursor comprising particles having a mean diameter of between 1.5 and 15 microns is treated under a reducing atmosphere, these particles comprising a mineral core and a shell based on a mixed phosphate of lanthanum and / or cerium, optionally doped with terbium, homogeneously covering the mineral core to a thickness greater than or equal to 300 nm, the heat treatment taking place in the presence, as a fluxing agent, of lithium tetraborate (Li 2 B 4 O 7) in a mass quantity of at most 0.2%, at a temperature of between 1050 ° C. and 1150 ° C. and for a duration of between 2 hours and 4 hours. |
