Recently, the Key Laboratory of Laser Materials at the Chinese Academy of Sciences' Shanghai Institute of Optics and Fine Mechanics has made significant progress in developing high-quality Ce:YAG scintillation crystals for high-resolution X-ray imaging systems. They have successfully produced scintillation crystal components with a diameter of 30 mm and a thickness ranging from 30 to 45 micrometers. In collaboration with the Shanghai Institute of Applied Physics, they developed an advanced X-ray detector utilizing ultra-thin Ce:YAG scintillation crystals, achieving high-resolution imaging under X-ray irradiation conditions (as shown in the images). Compared to similar crystals from Crytur, the Ce:YAG scintillation crystals developed by the Shanghai Opto-mechanical team demonstrate superior edge sharpness, enhanced image contrast, higher resolution, and overall better image quality under identical experimental conditions.
Crytur is a globally recognized company specializing in scintillation crystal growth, known for producing high-performance materials that are widely used in high-energy radiation detection and imaging. Their scintillation crystals are among the best in the world and hold a significant market share in this field. Ce:YAG, or Cerium-doped Yttrium Aluminum Garnet, is a highly regarded scintillation material due to its excellent luminescence properties. Beyond high-energy radiation detection, it plays a crucial role in fields such as high-energy physics, nuclear experiments, security screening, medical diagnostics, and military applications.
The successful development of ultra-thin Ce:YAG scintillation crystals marks a major milestone for the Shanghai Optics team, demonstrating their leading position in the field of high-performance scintillator devices. By working with top research institutions like the Shanghai Institute of Applied Physics, they aim to further advance the development of various high-energy radiation detectors with even better performance and broader application potential. This achievement not only highlights their technical capabilities but also opens new possibilities for future innovations in X-ray imaging technology.
