Lanthanum Fluoride

Lanthanum Fluoride sputtering target is a fluoride ceramic sputtering target composed of lanthanum (La) and fluorine (F), which can be made into different shapes with a variety of purity grades, and is mainly used for thin-film deposition, which is widely used in many industries such as decorative, semiconductor, display, LED, photovoltaic, optical information storage, glass coating, optical communication and so on.

Characteristics

High hardness: high hardness, so that it can withstand the bombardment of the ion beam in the sputtering process but not easy to deform or damage, which can ensure the stability and uniformity of the sputtering coating.

Good thermal stability: Lanthanum Fluoride can keep its structure and properties stable at higher temperatures, and will not change its physical properties significantly due to temperature changes during the sputtering process, which helps to maintain the quality of the coating.

High refractive index: Lanthanum fluoride is one of the few materials with a high refractive index in the far-ultraviolet (100 nm < λ < 200 nm) wavelength band, which makes it important for applications in optical coatings, where it is possible to prepare thin films with specific optical properties, e.g., for use in multilayer optical components such as ultraviolet dichroic and narrow band mirrors.

Good Optical Transparency: It has good optical transparency in a specific wavelength range, which can meet the requirements of optical devices on the optical properties of materials, and plays an important role in improving the transmittance and reflectance of optical films.

High chemical stability: lanthanum fluoride is a relatively stable chemical compound, not easy to react with other substances, and can maintain the stability of its chemical composition during sputtering, thus ensuring the purity and quality of the coating.

Water-insoluble: It is insoluble in water, which makes it less susceptible to the influence of moisture during preparation and use, and helps to maintain the performance of the material and the quality of the coating.

Applications

Semiconductor field: It can be used in the manufacturing process of semiconductor chips to form various functional films on the chip surface through sputtering coating, such as insulating film, conductive film, etc. These films play an important role in improving the performance and reliability of semiconductor devices.

Flat panel display field: in the liquid crystal display (LCD), organic light-emitting diodes (OLED) and other flat panel display device manufacturing, for the preparation of electrodes, optical films and other components, can improve the brightness of the display device, contrast and colour saturation and other properties.

Information storage field: for example, in the manufacture of information storage media such as hard discs and optical discs, magnetic films or optical films are formed on the surface of the storage media by sputtering coating technology, which improves the density and stability of information storage.

Optical lens coatings: coatings used in the manufacture of optical lenses, such as anti-reflective films and transmission-enhancing films, can reduce the reflection and scattering of light, and improve the transmittance and imaging quality of optical lenses.

Laser Optical Components: In the manufacture of laser optical components, such as resonant cavity mirrors and lenses for lasers, lanthanum fluoride sputtering targets can be prepared as thin films with specific optical properties to improve the performance and stability of laser optical components.

Wear-resistant materials: because lanthanum fluoride has high hardness and good wear resistance, it can be used to prepare wear-resistant coatings and applied to the surfaces of mechanical parts, cutting tools, etc. to improve their wear resistance and service life.

High-temperature corrosion-resistant materials: in high-temperature, corrosive environments, coatings prepared by lanthanum fluoride sputtering targets can provide good corrosion and oxidation resistance, protecting the base material from corrosion and oxidation.

High-grade decorative items: thin films with special optical effects and decorative properties can be prepared on the surface of metals, ceramics, glass and other materials, which can be used for the surface treatment of high-grade decorative items, jewellery and other items to increase their aesthetics and added value.
