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.
采用 980nm 激光激发，在 Ho(3+)/Yb(3+)/Er(3+)三掺杂氟碲酸盐玻璃中获得了 2.05μm 发射。在实验中观察到了强的近 2.05μm 处的发射，并根据荧光性能和吸收测量结果，对相应的能量传递机制进行了讨论和分析。Yb(3+)和 Er(3+)离子可以吸收泵浦能量，并将其有效地传递给 Ho(3+)离子。这些结果表明，这种 Ho(3+)/Yb(3+)/Er(3+)三掺杂氟碲酸盐玻璃在 2μm 激光方面有潜在的应用。
