In the whole history of human being, mankind is being dependent on light, from natural sunlight, flame light, incandescent lamp, to light‐emitting diode (LED). While light has become an integral part of human civilization, it is far away from fully understanding the light. Luminescence, a class of light emitted by luminophoric molecules and called as “cold” light unlike sunlight and torch light, not only can light up macroscopic space but can also help us to see the microscopic species such as cell and protein. Therefore, luminescence is a cutting‐edge research field in chemistry, materials, and biology. Countless chemists are committed to the design and preparation of new luminescence materials and their applicational development and mechanistic disclosure and have made a huge contribution to the progress of the scientific community.
