V Hal centres were studied by EPR in SrS doped with halogens after X‐raying the samples at 77 K. V Hal centre arises when a hole is captured by sulphide‐ion next to a cation vacancy with a halogen ion substituting the opposite sulphide‐ion. EPR parameters and thermal decay characteristics are measured for V Cl , V Br , and V I centres. The efficiency of different halogens to produce and stabilise cation vacancies is shown to vary for different alkaline earth sulphides. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
