Abstract
The invention relates to a non-linear optical molybdenum silver tellurite crystalloid and synthesis thereof. The crystalloid has the chemical formula of Ag2Mo3Te3O16 with the molecular weight of 1142.35, belonging to monoclinic system; and the space group is I2, and the unit cell parameters comprise: a=7.398 (6), b=11.296 (8), alpha=gamma=90 degrees, beta=97.730 (11) degrees, and z=2. The crystalloid is prepared by a hydrothermal method. The Ag2Mo3Te3O16 has excellent second-order non-linear optical performance, the powder SHG coefficient being eight times more than KDP and equivalent to KTP.
Description
Technical field
The invention belongs to nonlinear optical material and synthetic.
Background technology
Non-linear optic crystal has frequency-doubled effect (SHG), and selling off the high-tech areas such as information processing at laser frequency conversion, Electro-optical Modulation, light has significant application value.Nonlinear optical material is in modern science and technology, particularly in some military and civilian high-tech areas, such as the communication of submarine deep water, blinding laser weapons, the ocean locating fish, video disc recording, color laser printing, laser projection tv, photometry calculation and optical-fibre communications etc. has a series of important application.The non-linear optic crystal of at present practical application comprises α-LiIO
