Product Details
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 γ rays and α particles, Ce:YAG is
suitable for detecting light charged particles such as α particles,
electrons and βrays, 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, β and X-ray counting,
electronic and X-ray imaging screens and other fields.

——growing crystals, linking values
We are seller of crystals. At same time, we are producer of
crystals.
It is a long and arduous process from seed crystal to the desired
single crystal, the composition of the crystal changes through
three states and eventually grows into beautiful crystals. We
witness the growth process of each crystal and clearly know
technologies of each step in the crystal growth process, which
means that we can directly provide customers with crystals that
satisfied customer requirements.
We create value. At same time, we link value.
From company to individual, we all pursue the word "value".
Individual is valuable in society, enterprise is valuable in the
industry. We cherish the existence of value. We hope to set the
enterprise’ value as start pointing, expand to the surrounding,
extend the value from the customer to the supplier. Linking
enterprise and the industry more closer, to create more value.
