Keywords:phosphor, glass, ultraviolet

Using the high UV-C light transparent glass developed by Nippon Electric Glass, we made a wavelength conversion material in which UV excited phosphors were sealed and evaluated the optical characteristics. The wavelength conversion material in which two types of phosphors are sealed has broad emission in the UV region, and the emission spectrum can be freely designed by changing the mixing ratio or changing the type of the phosphor. The phosphor keeps its characteristic after glass sealed.
