Product Description


Ce:YAG single crystal is a fast decay scintillation material with excellent comprehensive performance, with high light output (20000 photons MeV), fast luminescent decay (~ 70ns), excellent thermal mechanical properties, The peak wavelength of luminescence (540 nm) matches well with the receiving sensitive wavelength of common photomultiplier tube (PMT) and silicon photodiode (PD), good light pulses distinguish between rays and particles, Ce:YAG is suitable for detecting light charged particles such as particles, electrons and rays, Especially, the good mechanical properties of Ce:YAG single crystal make it possible to fabricate thin screen with thickness less than 30 um.. Ce:YAG scintillation detectors are widely used in electron microscopy, and X-ray counting, electronic and X-ray imaging screens and other fields.

Ce:YAG Scintillator Crystal—A fast decay scintillation material used in white LED

Ce:YAG single crystal has obvious absorption peak at 340nm and 460nm, which is the characteristic absorption peak of Ce3+. At present, the emission wavelength of InGaN blue chip used in commercial white LED is 460 nm. The wide absorption band of Ce:YAG single crystal with a central wavelength of 460 nm indicates that it can effectively absorb blue light emitted from blue chip., The blue light emitted by the chip and the yellow light emitted by the Ce:YAG chip are superimposed to form white light. Moreover, Ce:YAG single crystal has good thermal stability, which is particularly important for the manufacture of high-power white LED devices.. With the increase of the thickness of Ce:YAG wafer, the light efficiency of white LED devices packaged with blue chip and Ce:YAG wafer increases gradually, and the color temperature and color rendering index decreases gradually., As the thickness of the wafer increases, the content of Ce3+ increases relatively. The more blue light is absorbed and the more yellow light is emitted, which results in the wafer’s luminescence changing from blue to white to yellow.
