摘要：

In present work, we succeeded in synthesizing new series of upconversion materials as Ba1-x (Ca/Sr)(x) GdF5: Er3+, Yb3+ by hydrothermal method. Surprisingly, we found that the doping of both ions can apparently affect the optical performance of these materials. The Ca2+ doping increases the proportion of green light while the Sr2+ doping increases the proportion of red light, which could be used in emission color tuning. Meanwhile, when the ion doping amount reaches 15%, the luminescence intensity of the two materials is 5-6 times higher than that of undoped materials respectively, which reveals that the luminescence efficiencies are great improved. This study testifies that this new series of Ba1-x(Ca/Sr)(x)GdF5: Er3+, Yb3+ exhibit great potential in the application of new developed upconversion materials.
