Recently, the world's leading manufacturer of Scintillator Crystal technology, DKCQ Optoelectronic Materials Technology Group has made a major technological breakthrough! The scintillation crystal material developed by this company has successfully reached the international leading level and achieved independent research and development of core material technology.
Scintillation crystals refer to crystals that can convert X, gamma rays or charged particles into ultraviolet or visible light photons to emit flashes. To put it simply, aim these high-energy rays, which are invisible to the naked eye, at the scintillation crystal, and it will really "flicker", playing the role of core components in high-end X-ray security inspection machines and medical equipment.
CTO Dr. Yuhan Ding introduced that this time DKCQ successfully realized the commercial production of 4-inch fast decay Ce:LYSO scintillation crystal material. Previously, China’s technology was immature and could not be mass-produced. DKCQ completed it in only 2 years. The process from R&D to production.

In addition, DKCQ took 7 years to develop the latest generation of scintillation crystal materials with independent intellectual property rights: a new type of scintillation crystal with large size and low afterglow (scientific name: 3-inch Ce:GAGG material). These scintillation crystals are key parts of a new generation of high-end X-ray security inspection machines, TOF-PET detectors, medical CT and other high-end equipment, which can greatly improve the accuracy and efficiency of security inspection and inspection systems.

DKCQ scintillation crystal materials has a strong R&D team: members are mainly composed of post-80s and post-90s, all with a master’s degree or above, including professionals in single crystal growth equipment manufacturing, crystal growth, performance characterization, processing and component production. The team is responsible Dr. Ding Yuxin, a senior engineer, is the original creator of the low afterglow CE: GAGG crystal. He took the lead in applying it to security inspections and industrial CT in the world, and made outstanding contributions to high-performance inorganic scintillation crystals.
"This technological breakthrough means that China's scintillation crystal material technology has reached the international leading level." According to Dr. Ding Yuli, China`s X-ray machines, CT machines and other medical and security inspection equipment, the core components of which were previously mainly from Japan’s Hitachi, Imported by companies such as Mitsubishi.
This breakthrough in research and development not only solved the "stuck neck" problem, but also led the development of the international security inspection industry. The production of large-size scintillation crystal materials has greatly reduced the production cost of crystal materials, on the one hand, it has solved the demand for high-end applications, on the other hand, it has raised technical barriers.
