SrF2-Crytal
►Description
Strontium Fluoride (SrF2) is one of the most important alkaline-earth fluorides. It has many physical properties, such as low energy phonon, high ionization, high resistance coefficient and good anion conductivity. It has been widely used in light-emitting devices, optical imaging, biomarkers, anion conductors and other fields. Compared with oxide and calcium fluoride, strontium fluoride has lower phonon energy, higher thermal conductivity and negative thermal optical coefficient, especially negative thermal optical coefficient, which can compensate the thermal lens effect in the process of laser oscillation. Strontium fluoride has promoted the research of optical materials and the improvement of optical instruments with its unique material structure and properties
