Abstract

The visible upconversion fluorescence centered at 548 nm, the ⁵F₄,⁵S₂→₅I₈ transition of Ho⁺³ was observed when a Tm/Ho co-doped silica fiber was pumped around the absorption band of 3F4 manifold of Tm⁺³. Excitation spectra were measured in the range of 730-860 nm. The infrared fluorescence around 2.03 μm, ⁵I₇→₅I₈ transition of Ho⁺³ was also measured to understand the role of energy transfer.
