Spectroscopic Properties of Ho³⁺ Doped in B₂O₃-SiO₂-SrO-Bi₂O₃-TiO₂ Glasses

Abstract:

A series of glasses with nominal composition in (53-x)B₂O₃:11SiO₂:34SrO:1Bi₂O₃:1TiO₂: xHo₂O₃ (BSSBT) where x = 0.0, 0.5, 1.0, 1.5, 2.0 and 2.5 mol% was synthesized by conventional melt quenching method. The as-prepared glasses have been investigated and reported for their physical and optical properties. The results show that, the densities and refractive index increase with increasing Ho₂O₃ content in the glasses. The absorption peaks of doped glasses were observed at a wavelength of around 420, 460, 480, 540, 640 and 900 nm which are assigned to ⁵I₈ ® ⁵G₅, ⁵G₆, ⁵F₃, (⁵F₄+⁵S₂), ⁵F₅ and ⁵I₅ transitions of Ho³⁺, respectively.
