Diphenyl ditelluride assisted synthesis of noble metal-based Silver-Telluride 2D organometallic Nanofibers with enhanced aggregation-induced emission (AIE) using oleylamine.

We have successfully synthesized 2D Silver-Telluride 2D organometallic nanofibers using diphenyl ditelluride (DPDT) as a precursor. The synthesis was carried out by reacting DPDT with AgNO3 in acetonitrile at room temperature (RT) under an inert atmosphere. The resulting material was fully characterized using various techniques, including UV-VIS-NIR spectroscopy, steady-state and excited-state fluorescent spectroscopy, IR-FTIR-ATR spectroscopy, HR ESI MS spectrometry, high-resolution transmission electron microscopy (HRTEM), BF-STEM or HAADF-STEM, and confocal fluorescence microscopy images and conductivity measurements. Initially, the nanofibers were almost non-emissive. However, we observed a remarkable modification after treating the nanofibers with oleylamine under ultrasound treatment. This treatment induced an aggregation emissive effect (AIE) in the solution and solid state, resulting in the formation of a highly red emissive fluorescent material. Overall, our findings demonstrate the successful synthesis of 2D Silver-Telluride 2D organometallic nanofibers and the induction of AIE in the resulting material through oleylamine treatment. This research provides valuable insights for developing new fluorescent materials with potential applications in various fields.
