• A kind of novel FP glass is prepared.
• The structure evolution caused by Yb3+ has been investigated.
• The near-infrared luminescence properties evolution caused by Yb3+ has been investigated.
• The quenching concentration of Yb3+ as the sensitizer is found in prepared system.
• The novel FP glass has good spectroscopic properties.
sThe near infrared luminescence properties of Yb3+–Er3+ co-doped fluorophosphate glasses have been investigated. The various effects on structure and 1.53 μm emission were analyzed as a function of Yb3+ concentration. The energy transfer mechanism was proposed. High measured lifetime (10.75 ms), large effective full widths at half maximum (73.71 nm) and large gain per unit length (62.8 × 10−24 cm2 s) have been achieved in prepared glass. The present glass co-doped with 6 mol% YbF3 and 2 mol% ErF3 showed magnificent luminescence properties for telecommunication application.
