The scintillator is the key material for various applications fields such as high-energy physics, nuclear medical imaging, and environmental monitoring. Despite of the great success in construction of various inorganic scintillators, the fabrication of the candidate with high active dopant solubility remains a great challenge. In this manuscript, we report a scintillating phosphate glass with extremely high Ce solubility of more than 20 mol%. It exhibits excellent radiation response properties not only to X-ray but also alpha particle. In addition, the material shows fast decay dynamics with the lifetime of 31ns. Furthermore, the materials also exhibit strong radiation stability and the continuous radiation exposure does not lead to obvious degradation. By using this material, their practical applications for X-ray imaging have been demonstrated. The results demonstrate that the Ce-doped phosphate glass show great promise for high-energy radiation detection.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
