Samarium Doped KMgF3 Nanoparticles
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.
