Dy 3+ White Light Emission Can Be Finely Controlled by Tuning the First Coordination Sphere of Ga 3+ /Dy 3+ Metallacrown Complexes
Single lanthanide(III) ion white light emission is in high demand since it provides the advantage of requiring only one chromophore for the control of the color. Herein, a series of Ga3+/Dy3+ metallacrowns (MCs) is presented, demonstrating outstanding white light colorimetric properties with CIE chr...

| description | Single lanthanide(III) ion white light emission is in high demand since it provides the advantage of requiring only one chromophore for the control of the color. Herein, a series of Ga3+/Dy3+ metallacrowns (MCs) is presented, demonstrating outstanding white light colorimetric properties with CIE chromaticity coordinates of (0.309, 0.334) and correlated color temperature (CCT) equal to 6670 K for the MC emitting the closest to the standard white color. Experimental data reveal that the CIE coordinates within the studied series of MCs are controlled mainly by the Dy3+-centered emission rather than by the ligand-centered bands, implying that Dy3+ can be tuned as a single ionic white light emitter by a simple modification of the coordination environment. |
