“…Metal iodates form a series of compounds potentially useful as dielectric materials and in non-linear optics [1][2][3][4]. They can also be employed for other applications like desalination and water treatment [5].…”

“…In addition, their properties are known to strongly depend on the growth conditions [11]. Transition metal iodates free of OH inclusions, e.g., Zn(IO 3 ) 2 , have thus been developed as alternative materials with high SHG efficiency [12]. It is generally accepted that the important electro and nonlinear optical properties of metal iodates originate from the lone electron pair of iodine in the IO 3 − iodate anion [13].…”

Synthesis, Characterization, and Crystal Structure Determination of a New Lithium Zinc Iodate Polymorph LiZn(IO3)3

et al. 2019

Synthesis and characterization of anhydrous LiZn(IO3)3 powders prepared from an aqueous solution are reported. Morphological and compositional analyses were carried out by using scanning electron microscopy and energy-dispersive X-ray measurements. The synthesized powders exhibited a needle-like morphology after annealing at 400 °C. A crystal structure for the synthesized compound was proposed from powder X-ray diffraction and density-functional theory calculations. Rietveld refinements led to a monoclinic structure, which can be described with space group P21, number 4, and unit-cell parameters a = 21.874(9) Å, b = 5.171(2) Å, c = 5.433(2) Å, and  = 120.93(4)°. Density-functional theory calculations supported the same crystal structure. Infrared spectra were also collected, and the vibrations associated with the different modes were discussed. The non-centrosymmetric space group determined for this new polymorph of LiZn(IO3)3, the characteristics of its infrared absorption spectrum, and the observed second-harmonic generation suggest it is a promising infrared non-linear optical material.

What is the most significant result of this study?In recent years, extensive research and continuous development have been presented on second-order nonlinear optical (NLO) crystal materials due to their potential applications in telecommunications, optical information processing, and optical data storage. In this study,t he first rare-earth iodate fluoride, Ce(IO 3 ) 2 F 2 ·H 2 O, has been synthesized, The results show that Ce(IO 3 ) 2 F 2 ·H 2 Oi sa ni odate fluoride with an ew structure and has potential applications in the field of nonlinear optics. What was the inspiration for this cover design?For us, the first encounter with geometry is on the blackboard at school. From that time on, we have been fascinated by the beauty of symmetry.C oincidentally,g eometric structures also inspire many chemists and play af undamental role in determining new ideas. Thus, this cover combines the elements of laser frequency doubling using an NLO crystal, the structure of Ce(IO 3 ) 2 F 2 ·H 2 Oa nd geometry to create a"surrealistic world".What other topics are you working on at the moment?We are currently focusing on the investigation of new photoelectric functional crystals, such as NLO and birefringent crystals. Especially,w et ry to design new compounds with excellent optical properties by the introduction of fluorine into, for example, iodates, borates, and phosphates. Extensive experiments prove that this is an effective design strategy to synthesize new materials.Invited for the cover of thisi ssuei sS hilie Pan and co-workers at Xinjiang Technical Institute of Physics and Chemistry,C hinese Academy of Sciences.
