The effect of MnCO₃ on the gain coefficient for the ⁴I_13/2 → ⁴I_15/2 transition of Er³⁺ ions and near-infrared emission bandwidth flatness of Er³⁺/Tm³⁺/Yb³⁺ co-doped barium zinc silicate glasses.

ABSTRACT: The roles of Mn²⁺ ions in the MnCO₃ compound, leading to the formation of an Mn²⁺-Yb³⁺ dimer and affecting the gain coefficient for the ⁴I_13/2 → ⁴I_15/2 transition of Er³⁺ ions and near-infrared (NIR) emission bandwidth flatness of Er³⁺/Tm³⁺/Yb³⁺ co-doped in SiO₂-ZnO-BaO (SZB) barium zinc silicate glasses, were investigated in this work. The composition of all elements from the original raw materials that exist in the host glasses was determined using energy-dispersive X-ray spectroscopy (EDS). Under the excitation of a 980 nm laser diode (LD), the NIR emission of Er³⁺/Tm³⁺/Yb³⁺-co-doped SZB glasses produced a bandwid
