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.
