Inside Cover: Multicolor Tuning of (Ln, P)-Doped YVO4 Nanoparticles by Single-Wavelength Excitation (Angew. Chem. Int. Ed. 5/2008)
Two complementary approaches to tuning emission colors are based on a single source of YVO4 nanoparticles doped with Ln and P ions, as described by X. Liu and co-workers in the Communication on page 906 ff. The emission wavelengths and intensity ratios of the emission bands can be precisely controlled by the choice of dopant (Ln=Eu, Dy, Sm) and control of dopant concentration. In this manner, the color of emitted light can be easily tuned under single-wavelength excitation.
