Luminescent material

A luminescent material comprising a luminescent particle for generating light, wherein the luminescent particle has an irregularly structured particle surface for improved outcoupling of the light generated within the luminescent particle, the luminescent particle comprises a first luminescent material having a first surface, and a second material that creates the structured particle surface upon the first surface, the second material comprises at least one material of the group of CaHPO4, MgAl2O4, YPO4, and LuPO4, and the structured particle surface comprises at least one structure that has at least one point with a height difference of more than 10 nm relative to a point in a local environment around the structure.

A luminescent material comprising a luminescent particle for generating light, wherein the luminescent particle has a structured particle surface for improved outcoupling of the light generated within the luminescent particle, and wherein the luminescent particle consists of a single material, wherein the structured particle surface comprises at least one structure that has at least one point with a height difference of more than 10 nm relative to a point in a local environment around the structure.
