Tb_x-Zn_1-x-BDC MOF films synthesized in-situ by the aero-sol-assisted chemical vapor deposition

Abstract

Tbx-Zn1-x-BDC MOF films were deposited in-situ on glass substrates by the aerosol-assisted chemical vapor deposition technique (AACVD) using an ultrasonic spray pyrolysis system, with x in the range of 0 to 1. Different precursors and solvents were used for the precursor solutions, which were deposited on a substrate using a controlled nebulization system. The obtained films were characterized using techniques, such as X-ray diffraction, Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR) and photoluminescence spectroscopy. The results revealed the evolution of the Zn-BDC and/or Tb-BDC crystalline structures in the films, as well as the changes in the physical properties of the Metal-organic frameworks (MOFs) such as thickness and roughness of the films. Furthermore, these findings provide important information for the design and control of MOF films with specific properties and their potential application in various fields.
