3) preparation and application.
Background technology
(Nonlinear Optics is a frontier of contemporary optics NLO) to nonlinear optics, is the research response of material and science of the nonlinear relationship that field intensity appears under the high light effect.In numerous nonlinear optical effects, frequency-doubled effect (SHG) be the most noticeable also be the nonlinear effect of studying at most.Optical material with nonlinear effect is in modern times in the science and technology; In particularly some civilian and military high-tech areas; For example photoelectricity communication, optical information storage, integrated circuit, photoswitch, light limiter, color laser printing, blinding laser weapons, the ocean locating fish etc. all have a series of important application.
Research shows that the compound that borate compound is compared other type more is prone to form non-centrosymmetrical structure, but not the structure of the heart is the precondition that produces nonlinear optical effect.Therefore, for a long time, the borate crystal of nonlinear optics is people's a research focus always.The nonlinear optics borate crystal of practical application comprises LiB at present
3O
5(LBO), β-BaB
2O
4(BBO), BiB
3O
6(BIBO) etc.Though these nonlinear optical materials are widely used in all trades and professions, yet different fields is also different to the requirement of nonlinear optical material, therefore can not have single nonlinear optical material optimization to be applied to all fields.This has just proposed requirement to the diversity of nonlinear optical material, so that can the specific nonlinear optical material of optimized selection in specific field.So be necessary to continue to seek and develop new nonlinear optical material.We are through adopting the AlO of chirality
4The boron anion bunch coordinated groups of gathering of the group and the non-heart is dressed up the strategy of the non-heart or chiral structure, thereby has obtained the novel non-linearity optical material of superior performance.
Summary of the invention
The objective of the invention is to prepare a kind of non-linear optical crystal diethyldithiocarbamaaluminum aluminum pentaborate (chemical formula: [Al (B
4O
9) (BO)] NH
3CH
2CH
2NH
3), its technical scheme is following:
We select aluminium isopropoxide (Al (i-PrO)
3), boric acid (H
3BO
3), ethylenediamine (C
2H
8N
2) make raw material, its mol ratio is 1: 6: 15, adopts water and pyridine to make mixed solvent, the chirality AlO that utilizes aluminium isopropoxide to be hydrolyzed into
4The collaborative assembling of the non-the heart-yin ion cluster that group and boric acid aggregate into, and make counter ion counterionsl gegenions with the ethylenediamine of diprotonization (abbreviate as oneself two ammoniums) kation, under hydrothermal condition, obtain the crystalline material of second two ammoniums five aluminium borates.
We record the mono-crystalline structures of this compound, and its structural parameters are following:
Chemical formula is [Al (B
4O
9) (BO)] NH
3CH
2CH
2NH
3, molecular weight is 303.15, belongs to monoclinic system, space group Pc, cell parameter are a=6.667 (4), and b=8.151 (4),
α=γ=90 °, β=97.949 (8) °,
Z=2.
The structure of second two ammoniums five aluminium borates is by AlO
4, B
4O
9, BO
3Be connected to a compound AlB through being total to the summit
5O
13Bunch, each AlB
5O
13Bunch identical with on every side six bunch links to each other and forms and have the three-dimensional spacious skeleton structure of 10 yuan of rings and 9 membered ring channels, and the ethylenediamine of diprotonization is filled in 10 membered ring channels as counter cation.
The nonlinear optics measurement shows that second two ammoniums five aluminium borates have good non-linear optical property, the very strong 532nm green glow of output under the 1064nm laser radiation, and its powder SHG coefficient is 1.9 times of KDP, and is suitable with LBO.
Second two ammoniums five aluminium borates provided by the invention are the crystal that grow through water (agent) process for thermosynthesizing.The material preparation method that the present invention adopted has that technology is simple, productive rate is high and advantage such as good reproducibility.The advantage of this material is not to be soluble in general solvent, and heat decomposition temperature point high (can be stabilized to 380 ℃ in the air atmosphere), light absorption is low, transparency range is big.
The prepared nonlinear optical material of this invention can be applicable to laser frequency conversion, electrooptical modulation, light and sells off high-tech areas such as information processing.
