TAC Self-Developed Czochralski Crystal Furnace
Taiwan Applied Crystal developed the Czochralski crystal growing technology through industry-academic cooperation with with National Sun Yat-sen University.
The crystal growing system includes an intermediate frequency power supply, heating furnace, a pulling machine and an automatic control program.
Adopting radio frequency induction heating, in addition to higher electrothermal conversion efficiency, it can also control the crystal growth temperature in real time.
The weight feedback to diameter control technology can control the crystal diameter automatically and accurately.
High reproducibility, suitable for mass production of crystal growth.
The exclusively developed thermal field design retains a lot of flexibility for
The crystal growth can be observed immediately. In addition to monitoring the crystal growth, it also reduces the difficulty of seeding operations.
The unique hot loading technology can replenish new raw materials while heating up the molten material. In addition to prolonging the life of the crucible, it can also increase the yield.
There are 8 TAC Self-Developed Crystal Growing Systems (CGS) currently in factory.
Totally 20 CGS will be established in 2025.
Crystal growth environment, thermal gradient in furnace is crucial. Crucible location in the heating coil. Multilayers thermal isolation to reduce heat dissipation
LYSO:Ce:Ca SCINTILLATING CRYSTAL
Ca co-doped with Ce:LYSO:
With calcium (Ca) doped into Ce:LYSO, the electrovalence of Ce is further uniformly distributed. The light yield of Ce:LYSO co-doped with Ca is improved, thus shorten the decay time
NSYSU authorized TAC to manufacture Ca co-doped with Ce:LYSO
The tender who did not provide the patent authorization to supply the Ca co-doped with Ce:LYSO is likely to violate the patent protection
