Abstract

Abstract: The valence change of samarium from trivalent to divalent state in strontium borates (SrB6O10) prepared in air was observed. The high resolution spectra of Sm2+ in matrix were studied between 10 K and 300 K. The results showed that three crystallographic sites for Sm2+ were available in the host. Energy transfer among these sites was possible. The vibronic transition of 5D0→7F0 of Sm2+ was studied at room temperature and the Huang-Rhys factor S was calculated. Due to the thermal population, 5D1→F0 transition at room temperature was observed.
