ResumoThe luminescence of Sm2+ in SrB4O7 was studied as a function of temperature from 10 K up to 600 K. According to the high-resolution spectra of Sm2+ in matrix at 10 K, the line numbers of 5D0–7FJ transitions were 1, 3, 5 for J=0, 1, 2, respectively. The 5D1–7FJ (J=0, 1, 2) transitions were observed at high temperature. The intensities of 5D1–7FJ transitions increased up to 400 K and then decreased with increase in temperature. 4f5d1–4f6 transition of Sm2+ appeared at high temperature.
