Mn²⁺-doped CsCdCl₃ perovskite luminescent crystals with tunable afterglow time, high efficiency and stability were synthesized by a hydrothermal method. CsCdCl₃ : Mn²⁺ shows the longest afterglow time of 1480 s and the highest PLQY of 91.4 %. CsCdCl₃ : Mn²⁺ maintained over 90 % of the PL intensity at 423 K, and the PL remains about 80 % after soaking in water for 55 days.
