| Tóm tắt: | 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 bandwidth of about 430 nm covering the O, E, and C bands. The effects of Mn2+ ions and
the Mn2+–Yb3+ dimer on the gain coefficient for the 4I 13/2 / 4I 15/2 transition of Er3+ ions and bandwidth
flatness of NIR emission of Er3+/Tm3+-co-doped and Er3+/Tm3+/Yb3+-co-doped SZB glasses were also
assigned. The optimal molar concentration of Mn2+ ions was determined such that the NIR bandwidth
flatness of Er3+/Tm3+/Yb3+-co-doped SZB glasses was the flattest. In addition, the role of Mn2+ ions in
reducing the gain coefficient for the 4I 13/2 / 4I 15/2 transition of Er3+ ions was also calculated and discussed. |
