Optical Coating: Dysprosium fluoride can be used in the coating of optical lenses and mirrors to improve their optical properties, such as increasing the refractive index and reducing reflection.
Laser Materials: Dysprosium fluoride is used as a dopant in laser crystals in laser technology, and is used in the manufacture of optical devices such as laser amplifiers, which have the effect of amplifying laser light at specific wavelengths.
Fluorescent Materials: Dysprosium fluoride can be used to prepare fluorescent materials containing dysprosium metal ions, which has potential application value in the field of illumination and display, for example, it can be used to manufacture special phosphors.
Electronic Industry: Dysprosium fluoride can be used to prepare magnetic materials such as dysprosium magnets, which can be used in electronic equipment, electric motors, magnetic storage and other fields; it can also be used as the backlight of liquid crystal display.
VI HALBLEITERMATERIAL GmbH strictly implements a full-process quality control system, adheres to the principle of rework for defective products, and releases each batch of products only after passing detailed specification tests. We are committed to building a responsible supply chain by complying with REACH and ASTM standards, ensuring lot consistency, and establishing a complete documented traceability system.
Dysprosium Fluoride granules are packed in double vacuum bottles and cartons to ensure safe transportation.
DyF₃ granules should be strictly sealed or stored under vacuum in a dry environment, avoiding contact with moisture and oxygen to prevent moisture absorption and deterioration.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
