Dopant-Defect Engineering In Strontium Titanate-Based Materials, Keith Lehuta

Doctoral Dissertations

Strontium titanate is a wide gap oxide perovskite that has been studied for numerous applications. Its potential use as a photocatalyst is limited due to only being able to utilize UV light. The introduction of metal dopant ions has been shown to alter the band structure to allow visible light photocatalysis, as well as alter the materials properties for other applications. This work will look to better explain the process of transition metal dopant ion incorporation and how the dopant ion can affect the defect chemistry of the material. The use of dopant specific spectroscopies, such as electron paramagnetic resonance …
