Turn Off 62%, respectively, but the phosphorescence lifetime is also reduced to 36 ms and 32 ms (Figure , 3k, Table ). The AlCl3, GaCl3 and InCl3 also play a role in significantly increasing the phosphorescence wavelength, and the three-component materials are red-shifted by 41-60 nm compared with the 3-QL/BPO (Figure , Table ). Similar to 5-QL/BPO/M, from AlCl3 to InCl3, with the increase of the metal ion quality, the phosphorescence intensity gradually increases (Figure , Table ). In addition, AlCl3, GaCl3 and InCl3 can also increase the phosphorescence lifetime, from 108ms for 3-QL/BPO to 227 -294 ms for the three components materials (Figure , Table ). Although Cu(CF3SO3)2 and ZnCl2 can improve the phosphorescence properties of doped materials, the effect is not obvious. But it is worth mentioning that Cu(CF3SO3)2 can make the phosphorescence lifetime of the 3-QL/BPO/Cu(CF3SO3)2 reach 313 ms (Figure , Table ). For the other three groups of three-component doped materials (4-
