High charge carrier storage capacity and wide range X-rays to infrared photon sensing in LiLuGeO4:Bi3+,Ln3+ (Ln = Pr, Tb, or Dy) for anti-counterfeiting and information storage applications

This work not only reports Bi 3+ and/or Ln 3+ doped LiLuGeO 4 storage phosphors with excellent charge carrier storage capacity for information storage, but also deepens our understanding on afterglow and storage phosphors and luminescence mechanisms.
