Recent advances in F-containing iodate nonlinear optical materials

New iodate fluoride Rb2Ce(IO3)5F with nonlinear optical properties

“…This technique appears particularly fruitful in the search for NCS iodates containing fluorides. [18][19][20] Depending on the type of chemical bonding, the final compound may be considered as an iodate fluoride if fluorine is bonded to a metal. In contrast, it is a fluoro-iodate if the fluorine atom is bonded to the iodine atom in the +5 oxidation state.…”

“…In contrast, it is a fluoro-iodate if the fluorine atom is bonded to the iodine atom in the +5 oxidation state. 18,20 The influence of iodate fluorination may be the reason for the following phenomena: (a) partial substitution of oxygen atoms in the iodate group may increase the polarizability of the iodine coordination polyhedron and increase the SHG signal; and (b) fluorination should increase the band gap for the final material and shift its absorption edge into the UV region. 18 About 50 iodate fluorides and fluoroiodates known from the literature 18 decisively prove the fruitfulness of the combination of iodate units with 4f-elements, with many of these compounds (up to 69%) possessing NCS crystal structures.…”
