Recently, the team of Prof. Chen Guanying (member of the Key Laboratory of Microsystem and Microstructure Manufacturing of the Ministry of Education) of the School of Chemical and Chemical Engineering of our school published a report entitled "Dye Sensitization" at the Chemical Society Reviews organized by the Royal Society of Chemistry. A Tutorial Review of Dye-sensitized lanthanide-doped upconversion nanoparticles. The Review of the Chemical Society is one of the most influential and authoritative academic journals in the chemical and chemical sciences. Its latest release in 2017 was 38.618. The Tutorial Review paper aims to guide the education and commentary on the frontier emerging hot research fields in the world, with a view to attracting the attention and research of more global researchers. The first author of the thesis was Wang Xindong, a doctoral student of the 2016 grade of our school. Professor Chen Guanying was the only correspondent author, and my school was the first and only communication unit.
The paper is based on the research work of Professor Chen Guanying in this field in recent years. The key point is to solve the problem of narrow absorption range and weak absorption ability of the doped up-conversion nanocrystals of lanthanide-based metals, and reviewed the dye sensitization internationally in recent years. Advances in the field of lanthanide metal doped upconversion luminescence nanocrystals, in-depth theoretical studies on the energy transfer mechanisms of Förster and Dexter at the organic-inorganic interface of dyes and nanocrystals, and an overview of lanthanide metals in nuclear and core-shell structures The energy transfer process of doped nanocrystals in dye sensitization finally summarizes and prospects the application of dye-sensitized nanocrystals in photovoltaic cells, security anti-counterfeiting, near infrared card, bioimaging, and optogenetics. This work lays a foundation for the study of dye-sensitized lanthanide-based metal doped nanocrystals and leads the development direction of the discipline.
At present, lanthanide doped upconversion luminescent nanocrystals have the advantages of narrow emission spectrum, long luminescence lifetime, high photochemical stability, and large anti-Stokes shift, etc., in biological imaging, multimodal imaging, and tumor photodynamic diagnosis And solar cells and other fields show great potential for application. However, due to the intrinsic reasons of the narrow range of light absorption and the weak light absorption ability of the doped up-conversion luminescent nanocrystals, their application is greatly limited. In recent years, Professor Chen Guanying has proposed a method for sensitizing lanthanide-doped luminescent nanocrystals with a dye cascade to effectively solve this key scientific problem. It has also been successfully applied in the fields of near-infrared bioimaging, multicolor display, and photovoltaic cells. . Related research results were published in the Journal of the American Chemical Society (2016, volume 138, pages 16192–16195) and Nano Letter (2015, volume 15, page 7400–7407). Other international journals have attracted extensive attention from researchers at home and abroad. Given the importance of these tasks, Prof. Chen Guanying was invited to publish the first Tutorial Review paper in the direction of the “Chemical Reviewâ€.
