title: Emission Enhancement and Color Tuning for GdVO4:Ln3+(Ln = Dy, Eu) by Surface Modification at Single Wavelength Excitation.
abstract: The surface modification can realize systematically the emission enhancement of GdVO4:Ln3+(Ln = Dy, Eu) microstructures and multicolor emission at single component. The structure, morphology, composition, and the surface ligands modification of as-prepared samples were studied in detail. It is found that the surface-modified ligands can act as sensitizer to improve the emission of the Eu3+and Dy3+ions via the energy transfer besides the VO43--Eu3+/Dy3+process. More importantly, under a single wavelength excitation, the emission color can be effectively tuned by manipulating the doping ratio of the Eu3+ions in the internal crystal lattice and the Tb3+ions in the external surface ligands, simultaneously. And further, multicolor emissions are obtained under single wavelength excitation due to the high overlapping between the VO43-absorption and the π-π* electron transition of the ligands. These findings may open new avenues to design and develop new highly efficient luminescent materials.
