Research progress on high refractive index optical resin
In recent years,high refractive index(n)optical resins have received widespread attention due to their excellent properties and have been widely used in advanced optoelectronic manufacturing.In this article,the design concept of increasing the n-value and Abbe number(v)of optical resins was emphatically introduced,and the basic methods and important parameters for developing high n-value optical resins were briefly introduced.The research progress of high refractive index resins in the past decade was reviewed,and the design principles of high refractive index optical resins as well as the research status of sulfur-containing,halogenated,phosphorus containing,organic-inorganic hybrid high refractive index optical resins were summarized.Some applications of high refractive index optical resins in optical adhesives,light-emitting diode(LED)packaging materials,optical lenses,etc were also listed.Finally,the future development of high refractive index optical resins was prospected.
