Achieving Ultraviolet C and Ultraviolet B Dual‐Band Persistent Luminescence by Manipulating the Garnet Structure (Advanced Optical Materials 5/2022)

In article number 2102157, Xianli Wang and Yuanbing Mao attained persistent luminescence (PersL) with dual UVC and UVB bands with maxima at 266 and 311 nm over 12 hours upon being charged at 254 nm from Pr3+-doped yttrium aluminum garnet through co-substitution. The generally hard to achieve long-lasting PersL at the high-energy spectral end is expected to play an irreplaceable role in outdoor long-distance self-sustained “solar-blind” imaging and other UV-triggered applications towards persistent sterilization and photocatalysis.
