Embodiment 1

[0020] Synthesis of α-AgI by Hydrothermal Synthesis 3 o 8 the crystal

[0021] AgNO 3 (0.05mmol, 8.5mg), I 2 o 5 (6.0mmol, 2002.9mg) and H 2 O (1.6mL) was put into a hydrothermal reaction kettle, sealed, and placed in a box-type resistance furnace. After 10 hours, the temperature was raised from 30°C to 210°C, and the constant temperature was reacted for 72 hours, and then dropped to 30°C at a rate of 3°C per hour. °C, filter and wash to obtain colorless flaky α-AgI 3 o 8 crystals (see image 3 ). The obtained crystal is ground into powder, and it is subjected to powder X-ray diffraction test, and the obtained collection of patterns ( figure 2 In b) and the X-ray diffraction pattern obtained by fitting the crystal structure ( figure 2 In a) completely consistent.

According to the cell parameters, a= 8.1443(3) , b=9.1171(3) , c=11.7005(5) , and z=4. According to the size of a crystal cell, V=773.50(5) <3>. The colorless sheet crystal alpha-AgI3O8 is obtained by the adoption of the hydrothermal method, and the SHG of the crystal alpha-AgI3O8 is 9 times that of KDP(KH2PO4).

Description

technical field [0001] The invention relates to a novel nonlinear optical crystal material. Background technique [0002] Nonlinear optical crystals are the material basis for realizing nonlinear optical effects. The use of nonlinear optical crystals can convert the frequency of the laser, broaden the scope of the laser light source, and expand the application field of the laser. The wide application of laser technology and the in-depth study of nonlinear optics have strongly promoted the development of nonlinear optics crystal materials. At present, among a large number of nonlinear optical crystals that have been reported, KH 2 PO 4 (KDP), KTiOPO 4 (KTP),β-BaB 2 o 4 (BBO), LiB 3 o 5 (LBO), α-LiIO 3 etc. have achieved industrial production, and have a series of important applications in several military and civilian fields, such as laser weapons, nuclear fusion laser drive, optical communication, optical storage, laser printing, etc. [0003] Iodide is a hot syste...
