Purpose: The purpose of this work is to prepare Titanium Oxide (TiO₂) with eco-friendly synthesis and also to study on structural, morphological, photoluminescence properties on Tb doped TiO₂.
Methodology: Titanium Oxide was prepared by orange fruit aqueous extract as a reducing agent with addition of terbium as its dopant. Characterization of the synthesized TiO₂ was done by XRD proving that the TiO₂ was in the structural form of rutile as evidenced by the sharp peaks. The relationship between the concentration of Tb dopant and the grain size of the film layer was studied. SEM Morphological analysis indicated the formation of particle cluster at 1100°C. EDX spectroscopy was employed to determine the position of elements of the samples while FTIR spectroscopy was in agreement with carbonyl and hydroxyl groups being absent in the prepared samples. Optical characteristics of the samples were evaluated by photoluminescence measurements under the excitation of 400 nm wavelength.
Findings: The results obtained in the present study pointed out how the terbium doping affected the structural and optical characterization of the TiO₂. An increase in the Tb concentration led to an increase in the grain size of the synthesized spherical film. Photoluminescence spectroscopy results showed two separate green and red emissions and was measured to have the highest intensity at 4% terbium concentration. From these results we can see the prospect of using Tb-doped TiO₂ in applications that require certain changes in the optical parameter.
Contribution to Theory, Policy, and Practice: This work contributes to the body of knowledge on green synthesis methods for nanostructures and the effect of RE doping in improving the properties of a material. The results provide insight for green synthesis of photo luminescent materials, optoelectronic devices, and monitoring instruments, identifying ways to pursue environmentally friendly material design.
