•The new Ho3+/Yb3+/Er3+ triply doped fluorotellurite glass is prepared.•Strong 2.05 μm emission can be obtained in the triply doped samples.•Efficient energy transfer can happen in the triply doped sample.•Detailed energy transfer processes have been discussed.
The 2.05 μm emission has been obtained using a 980 nm laser excitation in Ho3+/Yb3+/Er3+ triply doped fluorotellurite glass. Strong emission near 2.05 μm is demonstrated and the corresponding energy transfer mechanisms are discussed and analyzed according to the photoluminescence performance and absorption measurements. Yb3+ and Er3+ ions can absorb the pumping energy and transfer it to Ho3+ ions efficiently. These results indicate that this Ho3+/Yb3+/Er3+ triply doped fluorotellurite glass has potential applications in 2.0 μm laser.
