Abstract:
A copper complex containing mixed ligands [Cu(MCA)(Phen)·3H2O)] (HMCA = 3-hydroxy-2-methylquinoline-4-carboxylic acid, Phen = 1,10-phenanthroline) was prepared by the hydrothermal method. Structure was characterized by single crystal X-ray diffraction. Solid state fluorescence photoluminescence measurement shows a strong emission peak at 620 nm, which is attributed to the characteristic electronic transitions and molecular stacking effects within the ligand. CIE color difference analysis indicates that the title complex exhibits red photoluminescence (chromaticity coordinates of 0.1256, 0.2418). In addition, solid-state UV-Vis diffuse reflectance experiments revealed that the titled complex has an energy band gap of 1.578 eV.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
