CeF3
As a good Faraday rotator single-crystals, cerium fluoride (CeF3) have attracted much attention in the field of magneto-optics due to their broad applications such as optical isolators. The magneto-optical effects of the Ce ions are known to be caused by the intra-ionic parity allowed electric dipole transition between the 4fN and 4fN-15d1 configurations. These transitions are close to the absorption cut-off in the widely transparent fluorides, which leads to outstanding Verdet constants in the UV wavelength region. It is a good scintillation crystal with high density and short decay time. CeF3 Crystal is a suitable material in the measurements application of high counting rate, strong absorption irradiation and high time resolution process.

Dear Sir/Madam,
My name is An Tran, a postdoc at the Physical and Theoretical Chemistry Laboratory, University of Oxford.
We are looking for a CeF3 (Cerium Fluoride) crystal (thickness of ~1-2 mm). The crystal will be inserted into a cavity working at 532 nm, thus anti-reflection (AR) coating on both sides of the crystal is required with a reflectivity (per surface) as low as possible (R < 0.1%).
If your company can offer such customized crystal, could you please give us a quotation ?
In case the AR coating process is not available from your company, please also give us the price for the non-AR coating crystal.
Best regards,
Yes,We can grow CeF3 crystal by ourselves.Also,Coating process is available, We have coating equipments and related engineer.
SORRY to reply you so late. Our sales will mail to you.
Best regards,
