Lead halide perovskite CsPbX3 quantum dots have attracted a great deal of attention in recent years as new light-emitting materials because they exhibit high quantum efficiency and extremely sharp emission. Recently, we have reported that on-off fluorescence switching by photostimulation is possible by combining CsPbX3 quantum dots with photochromic molecules of diarylethene. In the talk, recent results on improving on-off switching efficiency and durability will be given.
