Rare earth up-conversion luminescence technology was shortlisted for the state technological invention award

The Ministry of Science and Technology released the preliminary evaluation results of the state science and technology awards, and “the establishment and multi-field application of real-time detection system based on rare earth nanoscale transmitting light technology” recommended by the Chinese medical association was shortlisted for the second prize. The project was developed by a project team supported by the academy of military medical sciences, Shanghai institute of optics and precision mechanics, Shanghai keyan optoelectronic technology co., LTD and Beijing rejing biotechnology co., LTD. The main team members are Yang ruifu, zhou lei, huang huijie, huang lihua, zheng yan and Lin changqing.
The so-called up-conversion nanomaterials are functional materials that can convert low-energy photons into high-energy photons. Rare earth up-conversion materials are favored because they can convert near-infrared light into visible light, and have become a research hotspot in biological applications. Many biomaterials researchers are committed to synthesizing up-conversion luminescent materials with high luminescence performance and applying them to biomarkers, cell imaging, lesion detection, DNA detection, biosensors, etc. There are two types of solar cells. One is the upconversion material, which converts far-infrared light into near-infrared light for the solar cell to absorb. The other is downconversion, or quantum clipping, which USES downconversion materials to convert ultraviolet light into 980nm of near-infrared light for solar cells to absorb.
Up-conversion materials have great application potential in the fields of biology, solar power generation and so on. Peking University, fujian institute of materials, tianjin branch of baotou rare earth research institute and other industry-university-research institutions have a large number of scientists and technicians to carry out related work.
