Preparation method of rare earth luminescent material with adjustable light color |
| abstract |
The invention discloses a preparation method of a rare earth luminescent material with adjustable light color, designs and synthesizes a large π-conjugated ligand L with terpyridine as the coordination site of rare earth ions, and the structure of the ligand is confirmed by 1 H NMR and MS . The metal coordination polymer L‑Ln was successfully prepared by the coordination polymerization of rare earth ions and terpyridine. The experimental study of fluorescence spectroscopy shows that L‑Eu has a luminescence behavior in response to the excitation wavelength. When the excitation wavelength is 295nm, a near-white light-emitting material is obtained, and the color coordinates are (0.41, 0.33). A rare earth luminescent material with adjustable light color can be obtained through modulation. |
