高透光性：氟化钡晶体在较宽的波长范围内具有优异的透光性能，使得它成为制造高性能光学元件的理想材料。
The combination of substantial transmittance, very low absorption, and minimal dispersion makes Barium Fluoride a here flexible and durable option for a number of optical factors, which include:
The calculated band buildings of BaF2 for the several pressures used from the experiments are proven in Fig. 6. Table one summarizes the Power gaps between the valence and conduction bands (valence‒conduction bandgap), the Main‒conduction bandgap, and the Main‒valence bandgap. While in the cubic section, once the utilized tension is less than three.seven GPa, the valence‒conduction bandgap appears to be secure. The valence‒conduction bandgap a little improves with growing pressure within the orthorhombic phase. Nevertheless, the conduction and valence bands don't appear to considerably flatten at the same time as the crystal is compressed. A serious prerequisite for CL would be that the valence−conduction bandgap ought to be bigger than the core−valence bandgap so which the CL photons are usually not reabsorbed by the material. Band hole Handle and band framework manipulation via uniform and uniaxial strain application were Beforehand demonstrated in hexagonal lithium calcium aluminum fluoride (LiCaAlF or LiCAF)26 and lithium yttrium fluoride (YLiF4)27 laser elements. Uniform quantity compression at expanding pressures nearly 50 GPa monotonically greater the valence−conduction bandgap of LiCAF due to flattening on the conduction band.
