Salt-inclusion chalcogenides: an emerging class of IR nonlinear optical materials.
The present challenges of creating new IR-NLO salt-inclusion chalcogenides and future perspectives in this field are discussed and the relationships between the non-centrosymmetric structures and NLO properties of these 3 types of compounds are summarized and briefly remarked.
