Tungsten Oxide

Tungstate scheelite structure is a kind of important laser material. They are tetragonal structures at room temperature and emit blue light from the tungstate crystals under UV excitation. The study shows that the structure of barium tungstate always keeps tetragonal structure from room temperature to melting (1820 K), indicating that it has good structural stability. In view of the superior properties of barium tungstate, barium tungstate thin films are often in short supply in the fields of luminescence and display technology, laser and photoelectron technology, and detection technology. In recent years, the electrochemical technology of galvanic cell has been used more and more in the field of preparation of inorganic functional films because of its advantages of one-step film forming, no post-processing and environmental coordination. Compared with electrolytic electrochemical technology, this technology has the advantage of zero energy consumption. Therefore, electrochemical ...

Barium tungstate is an important scintillation crystal material with excellent photoluminescence properties. Barium tungstate  has potential applications in the fields of nuclear spin hole, Raman scattering, solid-state laser and so on.  As the core component of the vacuum electronic device, the cathode must have the characteristics of large emitting current, low operating temperature, low evaporation rate and long service life, barium tungstate is a raw material that takes into account the high current, low evapotranspiration, long life cathode. Raman frequency shift technique is a nonlinear optical technique for obtaining a new wavelength laser by using the stimulated Raman scattering effect of Raman medium, barium tungstate crystal is a promising Raman crystal. In recent years, all solid state Raman lasers based on stimulated Raman scattering (SRS) effects of crystalline materials have become an attractive luminescent spot, the laser output from ultraviolet to...
