A rht-Type Luminescent Zn (II)-MOF Constructed by Triazine Hexacarboxylate Ligand: Tunable Luminescent Performance and White-light Emission Regulation through doping Eu3+/Tb3+

White-light emitting materials have become a hot research field of luminescent MOF (Metal-Organic Framework) because of its high practical application value. Herein, we successfully synthesized and characterized a rht-type fluorescent MOF Zn-TDPAT [H(6)TDPAT = 2,4,6-tris(3,5-dicarboxylphenylamino)-1,3,5-triazine] with a topology of (3, 24) connected nodes. A series of MOFs materials x%Tb + y%Eu@Zn-TDPAT were prepared by incorporating different concentrations of green emission center Tb3+ and red emission center Eu3+ into the blue-emitting Zn-MOF. The luminescence properties of MOFs materials x%Tb + y%Eu@Zn-TDPAT can be effectively adjusted by incorporating different concentrations of Tb3+ and Eu3+ and can obtain multi-color luminescence properties from blue, blue-green, green, yellow green, yellow, blue-red, yellow-red and white. According to trichromatic mechanism, by reasonably matching the intensity of blue light, green light and red light emitted by x%Tb + y%Eu@Zn-TDPAT at 420, 543 and 616 nm, MOFs materials 0.75%Tb + 5%Eu@Zn-TDPAT, 0.65%Tb + 5.5%Eu@Zn-TDPAT and 0.5%Tb + 7.5%Eu@Zn-TDPAT with white-light emission are obtained. Their CIE coordinates are 0.3162, 0.3345 (0.3162, 0.3345), (0.3138, 0.3339) and (0.3329, 0.3222), respectively, which are very close to ideal white-light emission (0.3333,0.3333).
