  Abstract

Preparation stable and continuous lanthanide metal–organic frameworks (Ln-MOFs) crystalline film coated on flexible substrate is a challenge for application. Herein a kind of novel nanoscale Eu-MOFs film on silk fabric for temperature sensing was successfully prepared. The silk fabric was coated with titanium dioxide (TiO2) via different atomic layer deposition (ALD) cycles, and then the Eu-MOFs can grow to nanoscale continuous film on the substrate. The composite was characterized by SEM, TEM, XPS, TG and PL. Fluorescence detection of temperature was also studied, and in a wide temperature range (77 K to 423 K), the fluorescence detection was sensitive and fitted to linear equation. In addition, the functional silk fabric exhibited different fluorescence detection behavior to temperature at different pH preparation conditions. At neutral preparation conditions, the fluorescence color of the functional silk fabric was dark yellow. The silk fabric exhibited rapid response in detection of temperature. At acidic preparation conditions, the fluorescence color was bright yellow, but it did not have detection effect. At alkaline preparation conditions, blue purple fluorescence was presented, and the temperature detection was also sensitive and fast. It is an effective method to obtain Ln-MOFs flexible film materials, and apply in the field of intelligent detection and wearing.
