Patent number: 11926775Abstract: This specification discloses methods of enhancing the stability and performance of Eu2+ doped narrow band red emitting phosphors. In one embodiment the resulting phosphor compositions are characterized by crystallizing in ordered structure variants of the UCr4C4 crystal structure type and having a composition of AE1?xLi3?2yAl1+y?zSizO4?4y?zN4y+z:Eux (AE=Ca, Sr, Ba, or a combination thereof, 0<x<0.04, 0?y<1, 0<z<0.05, y+z?1). It is believed that the formal substitution (Al,O)+ by (Si,N)+ reduces the concentration of unwanted Eu3+ and thus enhances properties of the phosphor such as stability and conversion efficiency.Type: GrantFiled: December 4, 2020Date of Patent: March 12, 2024Assignee: Lumileds LLCInventors: Peter Josef Schmidt, Philipp-Jean Strobel, Volker Weiler, Andreas Tücks
