Preparation and Characterization of Sm³⁺ Doped CBS Transparent Glass-Ceramics

Abstract:

Sm³⁺ doped transparent glass-ceramics of CaO-B₂O₃-SiO₂ (CBS) system were prepared and characterized.The precursor glass was prepared by melting method and annealed at 450°C for 2h and cooled to room temperature at a speed of 5°C/min.The appropriate heat treatment schedule to precursor glass was determined to be 2h at 600°C for nucleation and 3h at 810°C for crystallizition.The transmittion of glass-ceramics at the range of visable light is 68% in average. Five main emission bands of Sm³⁺ are centered around 564nm,605nm,646nm,679nm and 789nm,which correspond to the ⁴G _5/2→⁶H _5/2,⁴G _5/2→⁶H _7/2,⁴G _5/2→⁶H _9/2,⁴G _5/2→⁶H _11/2 and ⁴G _5/2→⁶H _13/2 transitions.Very strong luminescence at around 599nm is observed in glass-ceramics,This indicates glass-ceramics to be a better host for Sm3+ than precursor glass and a hopeful laser material.
