Abstract

In this study, we investigated the defect levels in the BaMgAl ₁₀O₁₇ and SrMgAl₁₀O₁₇ both theoretically and experimentally. The thermo-luminescence spectra showed the existences of the shallow and deep defect levels in the BaMgAl ₁₀O₁₇ and SrMgAl₁₀O₁₇ phosphors. The calculation results suggested that the structural defects such as oxygen vacancies would work as the trap for excited carrier. Moreover, the calculated binding energies and the formation energies of an oxygen vacancy suggest that the SrMgA₁₀O₁₇ and conduction plane can be degradated.
