“…The results obtained from our previous study [8] have demonstrated that the use of cathodoluminescence (CL) method allows identifying optimal content of phosphor(s). Such content is similar for intensive luminescence of non-radioactive samples and intensive self-glowing of radioactive crystals.…”

“…At the same time high content of alpha-emitter causes radiation damage of crystalline structure and finally, decrease of glowing intensity. The use of proper admixture of phosphor(s) allows essential increasing of glowing intensity and decreasing of radionuclide content [3,8]. However, if content of phosphor is too high the self-glowing is also suppressed.…”

“…Such durable materials may be safely used as sealed radioactive sources before their final disposal. For example, self-glowing durable crystals doped with small amount of radionuclides are advanced materials, which can find applications in optical couplers, robotics, medicine and other fields [2][3][4]. Intensive light emission might be converted into electric current that allows the 558 development of reliable "nuclear" batteries.…”

Durable crystalline actinide host phases of ceramic waste forms are considered as advanced materials which are prospective for safe use of Pu and minor actinides before their final disposal. Development of self-glowing actinide-doped materials with matrices that are chemically inert and resistant to radiation damage may significantly change the approaches to actinide immobilization. Single crystals of zircon doped with different amount of Tb and 238 Pu were synthesized by the flux method. Different non-radioactive crystals of Tb-doped zircon were studied first by cathodoluminescence method in order to identify the optimal content of Tb 3+ that provides the highest luminescence emission. Then self-glowing crystals of zircon were grown with the optimal Tb content and small admixture of 238 Pu (less than 0.1 wt. %). It was proposed that the valence state of Tb incorporated into zircon crystals can be (3+) and (4+), but only trivalent Tb is responsible for intensive luminescence. It is demonstrated that a small addition of Zr-phosphate to the flux supports Tb incorporation into zircon lattice and stabilizes preferably Tb 3+ . At the same time the addition of Zr-phosphate caused the crystallization of zirconia as a minor phase. Zircon crystals with very intensive self-glowing were successfully synthesized. The 238 Pu content was 0.02 wt.% and the Tb concentration varied between 0.2 and 0.3 wt.%. Zirconia crystals obtained from the same experiment are characterized by weak self-glowing, although the Tb content was only 0.02 wt.%, while the content of 238 Pu was comparable to that of zircon, i.e. 0.03 wt. %.
