We fabricated and characterized solution-route CeO2 thin films with tunable porosity and microstructure using inkjet printing technique. The films were deposited with different concentration inks and printing temperatures, resulting in varying thickness and microstructures. XRD characterization confirmed the formation of cubic fluorite structure in the printed films. This technique offers an advanced method for high-quality film fabrication with controlled microstructure and minimal waste of materials.
We report the fabrication and characterization of solution-route CeO2 thin films with a tunable porosity and microstructure. Films were deposited by means of inkjet printing technique using 0.2 M, 0.4 M and 0.6 M concentration inks prepared from Ce(NO3)(3)center dot 6H(2)O precursor. Printing was performed at two different temperatures of 60 degrees C and 300 degrees C to study the variation in structure. Printing parameters were adjusted for the consecutive deposition of layers, resulting in approximate to 140 nm and approximate to 185 nm thick single layers for 60 degrees C and 300 degrees C printing temperatures, respectively. We compared the microstructure of printed films for different concentrations, printing temperatures, solvents and substrates. The formation of the cubic fluorite structure of the printed films was confirmed via XRD characterization. We suggest this technique as an advanced method for high-quality film fabrication with a controlled microstructure and with a minimal waste of materials. Through adjusting printing parameters, both dense and porous films can be produced for use in different applications.
