抄録

The design principle for fluoride-containing optical devices for applications in the deep ultraviolet range is discussed. Variations in band gap energy, band structure and lattice constant of LiBa_xCa_ySr_(1−x−y)F₃ and Li_(1−x)K_xBa_(1−y)Mg_yF₃ have been studied. The band structure and transition type of these fluorides are predicted by ab initio band calculations based on the local density approximation. The lattice-matched double-hetero structure of direct-band-gap compounds LiBa_xCa_ySr_(1−x−y)F₃ on LiSrF₃ and Li_(1−x)K_xBa_(1−y)Mg_yF₃ on either LiBaF₃ or KMgF₃ is sufficiently feasible to fabricate.
