| titleOfInvention |
Composition comprising a cerium and/or terbium phosphate and sodium, of core/shell type, phosphor resulting from this composition and methods for preparing same |
| abstract |
The composition of the invention is of the type comprising particles formed by a mineral core and a shell that covers the mineral core uniformly, said shell being based on a phosphate of cerium and/or of terbium, optionally with lanthanum. The composition is characterized in that it contains sodium at a concentration of at most 7000 ppm. The phosphor of the invention is obtained by calcination of the composition at at least 1000°C. |
