Abstract: Phospher particles with a Protective Layer and a method for producing phosphor particles with a protective layer are disclosed. In an embodiment the method includes treating Si-containing and/or Al-containing phosphor with an acid solution, wherein a pH value of the acid solution is maintained within a range of pH 3.5 to pH 7 for a period of at least 1 h, wherein an Si-containing layer is formed on the phosphor particles, wherein the Si-containing layer has a higher content of Si on a surface than the phosphor particles, and/or wherein an Al-containing layer is formed on the phosphor particles, wherein the Al-containing layer has a modified content of aluminum on the surface than the phosphor particles and tempering the treated phosphor particles at a temperature of at least 100° C. thereby producing the protective layer.
