文摘

Spectroscopic studies were made on alkaline earth borate glasses. Three resonance signals corresponding to Cr3+ ions were observed. A broad signal (g = 5.110) belongs to Cr3+ ions located in the fully rhombic sites. Narrow signal (g = 1.960) belongs to the Cr3+ ions in cubic sites of the glass network. Very broad signal (g = 2.210) corresponds to the Cr3+ -Cr3+ paired centers.
