Abstract

In this paper we report the results from characterization and optical measurements on samarium doped KMgF3 nanoparticles. Photoluminescence (PL) is observed that can be attributed to Sm2+ and Sm3+. The Sm2+ temperature dependent PL lifetime data can be interpreted in terms of back transfer from the 5D0 level to the lowest 5d level followed by non-radiative decay from the 5d level.
