title: Efficient 2.05 μm emission of Ho3+/Yb3+/Er3+ triply doped fluorotellurite glasses.
abstract: The 2.05 μm emission has been obtained using a 980 nm laser excitation in Ho(3+)/Yb(3+)/Er(3+) 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. Yb(3+) and Er(3+) ions can absorb the pumping energy and transfer it to Ho(3+) ions efficiently. These results indicate that this Ho(3+)/Yb(3+)/Er(3+) triply doped fluorotellurite glass has potential applications in 2.0 μm laser.
