- Abstract
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 [H6TDPAT = 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).
