The lattice sites occupied by samarium ions in KMgF3 were ascertained. The relationship between valent state of samarium ion in hosts and substituted lattice sites was investigated using fluorescent spectra. It is found that the valent state of samarium in different cationic lattice sites is different. The internal relation between the valent state of samarium ion and occupied lattice site was discussed.
