Imparting Tunable and White-Light Luminescence to a Nanosized Metal–Organic Framework by Controlled Encapsulation of Lanthanide Cations
An alternative way
was demonstrated to fabricate highly luminescent
MOFs and white-light emitter by encapsulating lanthanide(III) (Ln<sup>3+</sup>) cations into the channels of Al-MIL-53-COOH (<b>1</b>) nanocrystals. The framework can serve as both a host and an antenna
for protecting and sensitizing the luminescence of the Ln<sup>3+</sup> cations. PXRD, TEM, FTIR, TGA, and N<sub>2</sub> adsorption measurements
were performed to determine the structure, thermal stability, and
BET surface area of the obtained products. The Ln<sup>3+</sup>-incorporated
nanocrystals show strong emission under UV-light irradiation, and
their luminescent properties were systematically studied. In contrast
to the essentially unchangeable luminescence of lanthanide-based MOF,
the luminescence of Ln<sup>3+</sup> @<b>1</b> allows design
and tuning. The versatile luminescence, good thermal stability, nanometer
size, and compatibility with aqueous condition reveal these materials
may have potential applications in LED lamps, barcoded materials,
and biological sensors. In addition, the thin films of Ln<sup>3+</sup>@<b>1</b> were prepared by chemical solution deposition (CSD)
from their metastabilized colloidal solutions, which open the way
to practical applications such as pellets and sensors for vapors
