Abstract：AlGaN based far-ultraviolet(FUV)LEDs with emission wavelength shorter than 250 nm have significant application potential in fields like safe sterilization and sterilization,non-invasive phototherapy,and environmental monitoring,and in recent years they have gradually become a new research hotspot in the ultraviolet LED field.This paper introduces recent advances at home and abroad in improving the luminous efficiency of AlGaN-based FUV LEDs,and provides a comprehensive analysis of the research and development challenges and technical solutions from the perspectives of epitaxial material growth,n/p-type doping efficiency,quantum structure design,light extraction efficiency and reliability.
