Description
technical field [0001] The invention relates to the technical field of chemical new material synthesis, and more particularly, to a zinc complex, a preparation method thereof, and an application as a near-ultraviolet photoluminescence material. Background technique [0002] Luminescent material, also known as luminescent body, is a functional material that can convert various forms of energy absorbed from the outside into unbalanced light radiation. Optical radiation can be divided into two categories: equilibrium radiation and non-equilibrium radiation, namely thermal radiation and luminescence. As long as any object has a certain temperature, the object must have radiation (red light, infrared radiation) that is in thermal equilibrium with this temperature. Non-equilibrium radiation means that under the excitation of some external action, the system deviates from the original equilibrium state. If the excess energy of the object is released in the form of light radiation ...
