Thank CTOnews.com netizens for the delivery of suitcase clues! CTOnews.com February 11 news, CNNC China Atomic Energy Research Institute recently successfully independently developed AIE (aggregation induced luminescence) isotope light source, its technology can reach the expected design target and works well in the application test, and the radiation conversion efficiency reaches 11%, which is 1.1 times that of the design target. This indicates that China has fully mastered the development technology of isotope light source and reached the international advanced level.

The self-developed new radioluminescent material isotope light source is a kind of self-luminous device which converts radioactive energy into light energy, which uses the charged particles released by the decay of radioactive materials to bombard the luminescent matrix. Compared with other electric light sources, the isotope light source has stable light intensity and does not need external power supply and maintenance, so it is an excellent light source for small field of view indication or lighting in dark conditions. It is suitable for places where there is no one on duty or where it is not easy to be electrified for a long time, such as night data reading of dashboards such as navigation and aviation, indoor and outdoor indication signs, light source components of radiation photovoltaic isotope cells and so on. it has a wide application prospect in many important fields such as national economy and science and technology.

The AIE isotope light source developed by the Atomic Energy Institute adopts a new aggregation-induced luminescence material instead of the traditional phosphor material, which provides a technical basis for improving the radiation conversion efficiency of the isotope light source and realizing the independent innovation of the isotope light source in our country. CTOnews.com learned that tritium is the most commonly used radionuclide in isotope light sources, and its luminous device has a service life of more than 10 years.

Through the basic research project "Isotope Radioluminescence based on aggregation-induced effect", the Atomic Energy Institute has made many original achievements. The design method of radioluminescence oriented AIE molecule is formed for the first time in China; combined with the radiation characteristics of radioactive source, the mathematical model of AIE radioluminescence is established and verified; the AIE radioluminescence material library is established and applied to the luminous layer of isotope light source; the first data software suitable for isotope light source is independently developed, which can be used for data transfer, structure design and simulation of isotope light source. For the first time in China, the microstructure of metamaterials is combined with isotope light source, which provides a new technical way to further improve the conversion efficiency of radiation.

The first isotope light source data integration software developed by ourselves next step, the project team will integrate AIE isotope light source into active optical sensing system to realize information detection with high sensitivity, high integration and low loss, which is of great significance for the design and application of MEMS and micro sensors.
