In article number 1905131, Woong Kim and co‐workers demonstrate a novel biomimetic strategy to realize wavelength‐dependent visualization of UV light. A nanopattern of three types of down‐shifting materials mimics the trichromacy of human vision derived from three kinds of cone cells and emits various colors depending on the wavelength of incident UV. This demonstration may contribute greatly to the...
The conversion of invisible ultraviolet (UV) light to visible light by down‐shifting (DS) materials has a variety of important applications in the fields of optoelectronics and photonics. The ability to control emission colors as a function of the wavelength of incident UV light would significantly advance scientific research and technological applications. A novel strategy for UV visualization is...
