This work reports the design of an efficient multiband UC system based on Ln3+/Yb3+-doped core-shell upconversion ...
focuses on the use of a special broadband near-infrared (NIR) phosphor, SrGa 12 O 19:Cr 3+. This phosphor emits NIR light that can persist for over two hours after ultraviolet irradiation has ...
This rapid growth drives the need for sophisticated tools to explore how materials interact with light across the ultraviolet (UV), visible (Vis), and near-infrared (NIR) spectrums. UV-Vis-NIR ...
