Abstract

In this study, we synthesized a solid solution of MOF, Eu_0.05Y_0.95-PTC (H₃PTC represents 2, 4, 6-pyridine tricarboxylic acid) by hydrothermal reaction, which showed exceptional stability under both weakly acidic and alkaline conditions and multiband luminescence. We further prepared Eu_0.05Y_0.95-PTC@PVA hydrogels by immobilizing Eu_0.05Y_0.95-PTC into a polyvinyl alcohol (PVA) aqueous solution, which exhibited both the integrity and temperature sensing behavior of the MOF solid solution, alongside excellent mechanical performance. Both Eu_0.05Y_0.95-PTC and Eu_0.05Y_0.95-PTC@PVA-8 hydrogel displayed temperature sensing capabilities over the range from 303 to 383 K, with relative sensitivities (S_r) reaching a maximum value of 1.94 %•K⁻¹ and 0.65 %•K⁻¹ at 383 K, respectively, and good recyclability as well.
