摘要：

Visible color tunable and white-light emitting Ln-MOFs were obtained via layer-by-layer epitaxial growth of different [Ln(2)(Mell)(H2O)(8)] compounds, where Mell is mellitate anion and Ln = Eu3+, Tb3+ and Gd3+. The RGB-MOF, RBG-MOF, BRG-MOF and BGR-MOF materials exhibit white-light emission and CIE coordinates (0.337, 0.336), (0.339, 0.330), (0.338, 0.337) and (0.333, 0.336), upon excitation at 361, 347, 378 and 360 nm, respectively. These values are very close to the standardized value of (0.33, 0.33).
