摘要：

Electron spin resonance methods are used to characterize a new Sn-impurity-perturbed W5+ centre with C-1 symmetry produced in ZnWO4 single crystals illuminated at 77 K with 365 nm UV light. The new centre is electron-Iike with its highest spin density at a W site, but also with a substantial spin density at an Sn impurity substituting for a neighbouring Zn cation. It is denoted as a W5+-Sn-Zn(4+) centre. The concentration of this defect is estimated to be less than 1 mu mol mol(-1).
