In this paper, Dy3+-doped ZnO nanocrystals have been synthesized via a simple combustion method. The as-prepared cuboid-like ZnO nanocrystals appear to be single hexagonal crystalline phase with an average diameter of 20 nm. The characteristic luminescence of doped Dy3+ ions has been evaluated, and the highly enhanced photoluminescence of Dy3+ ions can be obtained by Li+ doping.
