Fabrication of a surface plasmon resonance spectrometer for thin film characterization

Yong Zhao, University of Texas at El Paso


Basically, I put two separate projects in this thesis. From chapter 1 to chapter 7, I write about the whole process of building the surface plasmon resonance (SPR) instrument and its application. In chapter 8, I write about the synthesis of a porous titanium-niobium mixed oxide and its application in water decontamination via photolysis. For the first project, the SPR spectrometer was carefully prepared, designed and built in the Kretschmann prism configuration. A self assembled monolayer of 11-mercapto-undecanoic acid (MUA) was measured, which confirmed the accuracy of the SPR instrument with an experimental thickness of MUA at 1.9 nm. Also the unique construction of the SPR instrument provides the versatility of an open architecture design, which allows custom configurations, future modifications and performance enhancements. Finally the SPR spectrometer offers a powerful tool for future work to analyze the interaction between Mojave toxin and its antidote. For the second project (chapter 8), the porous oxide semiconductor material made of a titanium-niobium oxide is evaluated as a heterogeneous photocatalyst for the photolysis of organic compounds in water.
