With the rapid development of white LEDs,the research of new and efficient white light emitting materials has attracted increasing attention.Zero dimensional(0D)organic-inorganic hybrid metal halide perovskites with superior lumi-nescent property are promising candidates for LED application,due to their abundant and tailorable structure.Herein,[(CH3)3S]2SnCl6·H2O is synthesized as a host for dopant ions Bi3+and Sb3+.The Sb3+doped,or Bi3+/Sb3+co-doped,[(CH3)3S]2SnCl6·H2O has a tunable optical emission spectrum by means of varying dopant ratio and excitation wavelength.As a result,we can achieve single-phase materials suitable for emission ranging from cold white light to warm white light.The intrinsic mechanism is examined in this work,to clarify the dopant effect on the optical properties.The high stability of title crystalline material,against water,oxygen and heat,makes it promising for further application.
