PhD Studentship - Computational Discovery of Oxide Scintillators for High-Performance X-ray Detectors

University of Birmingham - School of Chemistry

This PhD project aims to computationally design improved transparent oxide scintillators for X-ray detection applications. New materials are needed for X-ray detectors because existing detector technologies face fundamental limitations in sensitivity, resolution, speed, and radiation hardness. Conventional materials like silicon or cadmium telluride often struggle with insufficient stopping power for high-energy X-rays, thermal instability, or issues related to toxicity and cost. As imaging demands increase—particularly in fields like high-throughput synchrotron science, medical diagnostics, and security screening—there is a critical need for detector materials that can combine high X-ray absorption, fast response times, and long-term stability. In this industrially sponsored PhD studentship, we have partnered with AWE to fund a 4-year Computational Project to use state-of-the-art Computational Chemistry techniques to understand structure-property relationships in oxide scintillators. We will use a wide array of computational techniques to understand the performance of the best known oxide scintillators for these applications, examine if their performance can be optimised, and use this knowledge to try to design novel compounds that can surpass the performance metrics of known materials.

The successful applicant should have or expect to achieve at least a 2.1 honours or equivalent at Bachelors or Masters level in Chemistry, Physics, Materials Science, or a related discipline. The successful applicant will demonstrate strong interest and self-motivation in the subject and the ability to think analytically and creatively. Good computer skills, plus good presentation and writing skills in English, are required. Previous research experience in contributing to a collaborative interdisciplinary research environment is highly desirable but not necessary as training will be provided. Experience of computer modelling is desirable but not essential as full training will be provided in an active and well-resourced research group based in brand new state-of-the-art Chemistry laboratories at the rapidly growing University of Birmingham.

Applications must be made through the university’s on-line application system www.birmingham.ac.uk/postgraduate/courses/research/chemistry/chemistry-phd.aspx. Please provide: (1) a cover letter summarising your research interests and suitability for the position; (2) the contact details of two people able to provide a letter of reference; and (3) a full curriculum vitae. The School of Chemistry is keen to achieve a gender and diversity balance across the School and welcome applicants from all backgrounds. The School holds an Athena SWAN Bronze Award, which recognises its work in promoting women’s careers in science, technology, engineering, mathematics and medicine (STEM). Applications will be accepted until 31 May 2026 but the position will be filled as soon as an appropriate candidate is found.
