研究目的
To synthesize and grow a new inorganic monometallic crystal namely zinc iodate with empirical chemical formula Zn(IO3)2 for nonlinear optical device applications.
研究成果
The grown ZI crystal is highly suitable for optoelectronic and photonic applications due to its nonlinear optical properties, mechanical strength, and dielectric behavior.
研究不足
The study is limited to the synthesis and characterization of zinc iodate crystal. The practical applications in devices are not explored in this study.
1：Experimental Design and Method Selection
The monometallic single crystal of zinc iodate [Zn(IO3)2] was grown by slow cooling technique. The solubility of ZI salt was analyzed for various temperature ranges from 40-60 oC.
2：Sample Selection and Data Sources
Zinc iodate salt was synthesized by taking potassium iodide (KIO3) and zinc chloride (ZnCl2) in stoichiometric ratio (2:1).
3：List of Experimental Equipment and Materials
ENRAF NONIUS CAD4 automatic X-ray diffractometer, Brukker IFS 66V Fourier transform infrared spectrometer, Perklin Elmer Lambda 35 UV-vis spectrophotometer, Q-switched Nd:YAG laser, KEITHLEY 6485 picoammeter.
4：Experimental Procedures and Operational Workflow
The prepared saturated solution of ZI was filtered using good quality filter paper and poured in a beaker with perforated lid and kept in a constant temperature bath. The temperature (40 oC) has been maintained for two days in order to achieve the homogeneity and then the temperature brought down at the rate of 0.1 oC per day to start growth process.
5：Data Analysis Methods
The optical band gap was evaluated by extrapolation of the linear plot. The SHG efficiency was measured using Kurtz and Perry powder technique. The mechanical parameters were determined using Vickers pyramid indenter.
