Embodiment 1

[0017] Embodiment 1 Potassium antimony zincate powder preparation

[0018] K will be weighed according to the metering ratio 2 CO 3 , ZnO and Sb 2 o 3 Grinding, mixing evenly, putting it into a platinum crucible, and reacting in a muffle furnace at 700°C for several hours, the pure phase can be obtained, and the yield can reach 100%.

Embodiment 2

[0019] The preparation of embodiment 2 potassium antimony zincate single crystal

[0020] K will be weighed according to the ratio of K: Zn: Sb = 4: 2: 2 2 CO 3 , ZnCO 3 with Sb 2 o 3 Grind, mix evenly, put it into a Pt crucible, put it into a box furnace at 300°C for pre-calcination, and grind it. Finally, keep the temperature at 800°C for 10 hours, then cool down to 700°C at a rate of 3°C per hour, and then drop to 500°C at a rate of 6°C per hour, and finally let it cool to room temperature naturally, and a lot of colorless and transparent materials are obtained at the bottom of the crucible. flaky crystals. Single crystal X-ray diffraction crystallographic analysis of this crystal shows that it is potassium antimony zincate, and the structure is as attached figure 1 shown. Its crystallographic parameters: its chemical formula is KZn 4 SbO 7 , molecular weight is 534.33, belongs to hexagonal crystal system, space group P6(3)mc, unit cell parameters are a=6.141(3), b...

Abstract

The invention relates to a non-linear optical material, belonging to the field of novel photoluminescence material. The crystalloid has the chemical formula of KZn4SbO7 with the molecular weight of 534.33, belonging to hexagonal system; and the space group is P6 (3) mc, and the unit cell parameters comprise: a=6.141 (3), b=6.141 (3), c=9.948 (6)*, alpha=90 degrees, beta=90 degrees, gamma=120 degrees, V=324.9 (3) *<3>, and z=2. The material is prepared by a high temperature solid phase method. The KZn4SbO7 has excellent non-linear optical performance, the powder SHG coefficient being three times more than KDP and the light emission wavelength covering the luminous range from purple light to red light and strong blue light, and is expected to become white light luminescent material.

Description

technical field [0001] The invention relates to a composite optical functional material integrating nonlinear optics and luminous performance and its synthesis. Background technique [0002] Nonlinear optical crystals, with frequency doubling effect (SHG), have important application value in high-tech fields such as laser frequency conversion, electro-optical modulation, and photorefractive information processing. Nonlinear optical materials are used in modern science and technology, especially in several military and civilian high-tech fields, such as submarine deep-water communication, laser blinding weapons, marine fish detection, optical disc recording, color laser printing, laser projection TV, optical computing and Optical fiber communication, etc., have a series of important applications. The nonlinear optical crystals currently used in practice include LiB 3 o 5 (LBO), β-BaB 2 o 4 (BBO), KH 2 PO 4 (KDP), KTiOPO 4 (KTP), LiNbO 3 (LNO) and BaTiO 3 (BTO) and s...
