Abstract

A terbium-based metal-organic framework (MOF) TbTATAB (H3TATAB = 4,4',4''-s-triazine-1,3,5-triyltri-p-aminobenzoic acid) with a 1D channel has been synthesized and structurally characterized. Then, the luminescent dye 7-diethylamino-4-methylcoumarin (C460) was encapsulated into the channel of TbTATAB by an exchange strategy to yield the dual-emitting MOF?dye composite TbTATAB?C460. Luminescence explorations demonstrated that the composite can be applied as a ratiometric thermometer over a wide temperature range from 100 to 300 K. The unique energy transfer between C460 molecules and Tb(3+) enables the TbTATAB?C460 thermometer to be highly temperature-sensitive with a maximum relative sensitivity of 4.484% K(-1) at 300 K. The composite luminescent thermometer is self-calibrated, colorimetric, reusable and much more thermosensitive than most of the other explored sensors.

Terbium (atomic symbol: Tb, atomic number: 65) is a Block F, Group 3, Period 6 element with an atomic radius of 158.92535.Terbium Bohr Model The number of electrons in each of Terbium's shells is [2, 8, 18, 27, 8, 2] and its electron configuration is [Xe]4f9 6s2. The terbium atom has a radius of 177 pm and a Van der Waals radius of 221 pm.Terbium was discovered and first isolated by Carl Gustaf Mosander in 1842. In its elemental form, terbium is a silvery-white soft metal. Terbium is found in cerite, gadolinite, and monazite. It is not found in nature as a free element. Elemental TerbiumTerbium compounds are brightly fluorescent, and a majority of the world's terbium supply is used for creating green phosphors that enable trichromatic lighting technology. It is also frequently used as a dopant for crystalline solid-state devices and fuel cell materials. It is named after Ytterby, the town in Sweden where it was discovered.
