Abstract

The invention relates to a tellurium-caesium molybdate crystal, growth of tellurium-caesium molybdate crystal by a flux method and application. The tellurium-caesium molybdate crystal belongs to a hexagonal crystal system, the space group is P63, and the crystal has penetrability within the wavelength range of 430-5380nm; the piezoelectric coefficient at room temperature is as follows: d33=20.5pC / N; and infrared laser with the wavelength of 1064nm generated by a Nd:YAG laser irradiates the crystal to generate strong green light. In the invention, crystal growth is realized by the flux method to finally obtain the large-sized monocrystal; and the obtained crystal is used for manufacturing a piezoelectric device and can be also taken as a nonlinear optical crystal, a ferroelectric crystal, a pyroelectric crystal and a laser host crystal.

Description

technical field

[0001] The invention relates to a novel piezoelectric crystal and its growth and application, in particular to cesium molybdate tellurium crystal, growth method and application, and belongs to the technical field of crystal materials. Background technique

[0002] The piezoelectric effect was developed by the Curie brothers in 1880 on α-SiO 2 It was first discovered on the crystal, and it reflects the mutual coupling between the elastic properties and the dielectric properties of piezoelectric crystals. When some dielectric crystals are deformed under the action of external force, different charges will be generated on some of its corresponding surfaces. This phenomenon that there is no electric field and only electric polarization due to deformation is positive piezoelectricity. effect. Due to the mutual conversion of mechanical properties and electrical properties, piezoelectric materials are used to make piezoelectric devices such as piezoelectric oscill...
