Metal-organic frameworks (MOFs) provide broad prospects for the development of various types of luminescence sensors due to their versatile structures and tunable luminescence characteristics. In order to overcome the main drawbacks of singleemission luminescence sensors, such as being susceptible to the fluctuation of probe concentration and interference from external conditions, the ratiometric luminescent sensors utilizing the ratio between the intensity of two emssions within the same luminescent material, have been widely developed in recent years. We are committed to designing and developing luminescent ratiometric MOF-based sensors toward a wide range of targeted functional species. In this mini-review article, after the general description of ratiometric luminescent sensors, we have summarized our recent advances in the strategies for synthesizing dual-emitting MOFs and their applications for ratiometric sensing of temperature, pH, biomarkers and water, as well as the related sensing mechanisms.

“…To overcome these problems, ratiometric uorescence T sensors have been developed. [8][9][10][11] Ratiometric sensing of T utilized two uorescence emission peaks as signal. Salas-Juárez et al reported a novel ratiometric uorescence sensor for monitoring T in the range of 25-100 C. Lanthanide complex Tb/Eu-TPTZ incorporated in polymethyl methacrylate (PMMA) matrix was used as T-response material.…”

“…This work may be considered as part of an exciting new trend, related to overcoming the previously-mentioned limit. Other approaches include the combination of linear and non-linear optics, whether by second-harmonic generation [ 14 , 15 , 16 ] or multilevel cascade [ 17 ], as well as the combination of a single-emission band and the conventional Boltzmann ratio [ 18 ].…”

A new Eu3+-doped Gd3+ complex of formula [Eu0.0135Gd0.9865(pta)3me-phen] was synthesized and structurally characterized (Hpta = benzoyltrifluoroacetone, me-phen = 5-methyl-1,10-phenanthroline). The photoluminescence study revealed that when the compound was excited at RT, under a 457 nm continuous laser, the material exhibited high luminescence due to the antenna effect of the ligands, as well as a good balance between the phosphorescence from the spin-forbidden triplet (from the organic ligands), and the characteristic lanthanide f-f transitions. The ratio between the previous emissions drastically changed when the sample was heated up to 62 °C inside a tubular furnace. This ratio was investigated using the luminescence intensity ratio method, to analyze the capabilities of the sample as a temperature sensor. The relative sensitivity reached a maximum of 11.4 °C−1 %, maintaining a detection limit below 0.15 °C for the whole temperature range.
