Abstract

The design of fluoride-based optical devices for deep ultraviolet applications is discussed. Variations in the band-gap energy and band structure with respect to composition are investigated for Li_(1-x)K _xBa_(1-y)Mg_yF₃ perovskites. The band-gap energy, lattice constant, and band structure of perovskitelike fluorides are estimated based on ab initio calculations within the local-density approximation. The lattice-matched double heterostructure with direct band-gap compounds (Li_(1-x)K_xBa_(1-y)Mg_yF ₃ on either LiBaF₃ or KMgF₃ substrates) is promising for fabrication.
