    摘要： The invention relates to a method for producing fluorescent particles of an Si-containing and/or Al-containing fluorescent material with a protective layer, having the following method steps: A) treating the Si-containing and/or Al-containing fluorescent material with an acid solution, wherein the pH value of the acid solution is kept within a range of pH 3.5 to 7 for a period of time of at least 1 h, and an Si-containing layer is formed on the fluorescent particles, said Si-containing layer having a higher content of Si on the surface than the fluorescent particles, and/or an Al-containing layer is formed on the fluorescent particles, said Al-containing layer having a lower content of Al on the surface than the fluorescent particles, and B) tempering the treated fluorescent particles at a temperature of at least 100 °C, thereby producing the protective layer. By using such a method, stable protective layers can be produced on fluorescent particles in a particularly simple manner.
