| titleOfInvention | fluorescent particles with a protective layer and a method for producing fluorescent particles with a protective layer |
| abstract | The invention relates to a method for producing fluorescent particles of a self-contained and / or al-containing fluorescent material with a protective layer, having the following method steps: a) treating the self-containing and / or al-containing fluorescent material with an acidic solution, wherein the ph value of the acidic solution is kept within a ph range of 3.5 to 7 for a time period of at least one hour, and wherein a silicon-containing layer is formed in the particles. fluorescent particles, said self-containing layer having a higher surface silicon content than the fluorescent particles and / or an al-containing layer is formed on the fluorescent particles, said al-containing layer having a lower surface al-content than the particles. and b) quenching of the treated fluorescent particles at a temperature of at least 100 ° C, thereby producing the protective layer. By making use of this method, stable protective layers can be produced in fluorescent particles in a particularly simple manner. |
