A big difference from single-component RTP materials is that the content of guest as emitter in the doped system is extremely low, while the content of host reaches 99%-99.99%. Actually, the host matrix is equivalent to a container in which guest molecules emit phosphorescence depending on the interaction with the container. Therefore, it is entirely possible to add a third or even fourth component to the host container, and use the interaction between the third component and the host or guest to control the phosphorescence lifetime, phosphorescence intensity and phosphorescence wavelength, or to construct the functional RTP materials. However, except for a few researchers who used water as the third component to construct the multi-component doped materials with strong phosphorescence emission by the formation of hydrogen bonds, the advantage that the host can be used as a container is ignored. Organic matters, especially which containing heteroatoms such as nitrogen, sulfur, and phosphorus, are easily coordinated with various metal ions. Therefore, the metal ions can affect or even regulate the luminescence properties of organic matters. Based on the above ideas, seven phenylquinoline isomers (n-QL) containing nitrogen atoms are designed as guests, and the benzophenone (BPO) with excellent crystallinity, lower melting point is selected as the host to construct a two-component doped system. Importantly, seven chloride salts of the same period or the same main family (Al 3+ , Cu + /Cu 2+ , Zn 2+ , Ga 3+ , Ag + , Cd 2+ , In 3+ ) are selected as the third component to coordinate with the guests. The doped materials n-QL/SDB without the metal salts have only very weak green phosphorescence, but when the metal salts are added to the system, the phosphorescence performance of the three-component doped materials are significantly enhanced. More importanly, utilizing the difference in the coordination ability of each metal ions with the nitrogen atom and the difference in its own weight, the phosphorescence performance of the doped material can be selectively adjusted. Ag + and Cd 2+ can greatly enhance the phosphorescence emission through the heavy atom effect, the phosphorescence intensity can be increased by up to 38 times. The strong coordination ability of Al 3+ , Ga 3+ , In 3+ and nitrogen atoms can significantly prolong the phosphorescence wavelength of the doped material, and the longest redshift can be 60 nm. And Cu 2+ , Ga 3+ , and In 3+ can extend the phosphorescence lifetime by a maximum of 3.6 times.
