Yttrium-Doped Barium Fluoride BaF2:Y
DESIOPTOE is a professional manufacturer of fluoride crystals. Leveraging advanced crystal growth technology, we produce yttrium-doped barium fluoride (BaF₂:Y) crystals with excellent optical and scintillation properties. Undoped barium fluoride exhibits an ultrafast scintillation decay of 0.8ns at 195nm and 220nm emission wavelengths, but also suffers from a slow decay component of around 660ns at 310nm, which limits its practical application. To suppress the slow decay, we introduce yttrium ions as dopants, producing Y-doped BaF₂ crystals. The yttrium doping effectively suppresses the slow scintillation component at 310nm in pure BaF₂ and enhances the scintillation efficiency under ionizing radiation. These outstanding optical and scintillation characteristics make BaF₂:Y suitable for applications in nuclear medicine, high-energy physics, radiation detection, and related fields.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
