研究了基于ZnF2薄膜的电致发光器件。从掺杂稀土离子(Sc、Y、La、Pm、Yb和Lu除外)的ZnF2薄膜中观察到电致发光。这些器件中的发射从紫外区到红外区都是可见的。在许多情况下，这些电致发光的颜色和光谱区域相对于硫化锌薄膜器件中的相同离子的电致发光向更短的波长移动。为了获得有关稀土离子激发过程的信息，还测量了其暂态行为。
Electroluminescent devices based on ZnF2 thin-films have been investigated. From the ZnF2 thin-films doped with rare-earth ions (except for Sc, Y, La, Pm, Yb and Lu), electroluminescence was observed. The emission in these devices was visible from the ultraviolet to the infrared region. The color and spectral region of these electroluminescences shifted to shorter wavelength compared with those of the same ions in the ZnS-based thin-film devices for many cases. To obtain information on the excitation process for rare-earth ions, the transient behavior has also been measured.
