其他应用：氟化钡还可用于制造电机电刷、光学玻璃、光导纤维、助熔剂、涂料剂珐琅等，以及作为木材防腐剂、杀虫剂、尸体防腐剂和固体润滑剂等。此外，氟化钡在开发高温超导器件方面也有重大作用。
BaF�?optical windows and mirrors are ideal for programs that have to have durability and significant transmittance across UV, seen, and IR wavelengths, rendering it common in spectroscopy and laser apps.
Inside the cubic phase, the CL emission peak at 221 nm a little bit redshifts to 226 nm because the stress will increase from 0.one GPa to three.7 GPa. The change to longer wavelengths of the CL peak (reliable black circles in Fig. 7b) is in keeping with the lessen during the Main−valence bandgap (sound grey circles in Fig. 7b; Table 1) for cubic BaF2 under pressure. The depth of CL emission seems being frequent as being the force is enhanced. At 3.seven GPa, exactly where BaF2 exists in both equally the cubic and orthorhombic phases, the luminescence emission depth is weakened. From the orthorhombic period, the luminescence emission intensity seems being stable, albeit weaker than the intensity inside the cubic phase, given that the pressure increases. Interestingly, the luminescence peak Plainly shifts to an extended wavelength by the stage changeover from your cubic stage to your orthorhombic phase (stable circles with sound traces in Fig. 7b, replotted as reliable circles in Fig. 7g; Table 2). At an applied stress of 5.0 GPa, a highest change to 238 nm is noticed. This shift is in keeping with the decrease during the Main−valence bandgap during the orthorhombic phase due to the downshift of your valence band (solid orange circles with dashed lines in Fig. 7b; Desk one). The observed broadening from the luminescence emission, specifically in the orthorhombic period, may very well be attributed for the enlargement of your valence bandwidth because the stress will increase. As revealed in Desk one, the width from the valence band (ΔEv) increases monotonically as being the force increases. At superior strain, the strengthened crystal subject can induce better band splitting and boost electron‒phonon coupling37. Certainly, preceding will work have noted comparable broadening in valence−conduction band photoluminescence emission38,39,forty, but This can be the initially report on broadening of Main−valence band luminescence.
Barium Fluoride delivers lower dispersion, that means it may transmit mild across a broad variety of wavelengths with nominal chromatic aberration or colour distortion. This causes it to be precious in significant-precision optical programs requiring accurate-to-coloration final results.
