The present article reports synthesis and spectroscopic analysis of Sm:BaB 4 O 7 microfibers embedded in borate glass. Structural analysis, using TEM, XRD techniques, revealed the formation of fibre shaped BaB 4 O 7 crystals. A bright red dominated orange-red emission was observed, on 355nm and 532nm excitations, in ceramic sample. Higher emission and absorption higher...
