Abstract

In this paper, a novel kind of tristrontium sodium antimony(V) oxide (NaSr3SbO6:Mn4+; NSSO:Mn4+) material was developed, whose crystal structure is different from the well-researched Mn4+-doped antimoniate double pervoskite materials. The optimal NSSO:0.006Mn4+ can be mainly excited using ultraviolet/near-ultraviolet (UV/n-UV) and partial blue lights with a high quantum yield of 46% upon 365 nm UV excitation and good temperature dependent performance.
