Highlights: • Novel Er{sup 3+} doped germanosilicate glasses were synthesized. • Excellent thermal stability and 2.7 μm emission properties were obtained. • High A{sub rad} (33.75 s{sup −1}) and emission cross section (1.90 × 10{sup −20} cm{sup 2}) were achieved. • A reasonable energy transfer mechanism was put forward. - Abstract: 2.7 μm fluorescence has been achieved for the first time in Er{sup 3+} doped novel germanosilicate glasses. Thermal stability, spectroscopic properties and energy transfer mechanism have been investigated in detail. Moreover, the spontaneous transition probability (A{sub rad}) and emission cross section of samples were calculated and analyzed. The prepared Er{sup 3+} doped germanosilicate glasses possessing excellent thermal stability, high A{sub rad} (33.75 s{sup −1}) and emission cross section of 2.7 μm (1.90 × 10{sup −20} cm{sup 2}) provide a new material for the realization of mid-infrared fiber lasers.
