[0010] Example 1: PbCl 2 (0.028 g, 0.10 mmol), Pt(acac) 2 (platinum acetylacetonate) (0.058 g, 0.14 mmol), I 2 o 5 (2.672 g, 8 mmol) and H 2 O (5 mL) was put into a hydrothermal reaction kettle, mixed evenly, sealed, and placed in a box-type resistance furnace. After 400 min, the temperature was raised from 30 °C to 190 °C, and the temperature was kept for four days. °C, light yellow transparent bulk crystals can be obtained.

The invention relates to platinum lead iodate serving as a second-order non-linear optical crystal. A chemical formula of the platinum lead iodate is PbPt(IO3)6(H2O), the molecular weight is 1,469.68, and the platinum lead iodate belongs to a trigonal system; and a space group is R3, a unicellular parameter a is equal to 11.307 (6) angstroms, b is equal to 11.307 (6) angstroms, c is equal to 11.242 (9) angstroms, alpha is equal to beta which is equal to 90 degrees, gamma is equal to 120 degrees, V is equal to 1244.79 (14) angstroms<3>, and Z is equal to 3. The platinum lead iodate [PbPt(IO3)6(H2O)] is prepared by a hydrothermal method and has the high second-order non-linear optical performance, and the powder second harmonic generation (SHG) of the platinum lead iodate is 8 times that of potassium dihydrogen phosphate (KDP).
