Abstract

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-yMg_yF₃ have been studied. The band structure and transition type of these fluorides are predicted by ab initia 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 LiBaFj or KMgFj is sufficiently feasible to fabricate.
