Regulating emission in Er doped silicate glass and fiber via coordination engineering

Journal of Materiomics
L-band Er doped fiber (EDF) laser sources are in great demand for extending communication bandwidth. However, the gain performance is limited by the low emission cross section (σe) of Er3+ at wavelengths longer than 1590 nm. In our study, we revealed the
