Abstract

We report first principles quantum-chemical calculations of the electronic structure of pure CaWO4 and CaWO4 containing oxygen vacancies. The calculation results are compared to values extracted from experimental thermoluminescence data. The influence of oxygen vacancies and structural disorder shows up as the presence of additional levels in the band gap of the material.
