| الوصف: | Electron spin resonance methods are used to characterize a new Sn-impurity-perturbed W5+ centre with C1 symmetry produced in ZnWO4 single crystals illuminated at 77 K with 365 nm UV light. The new centre is electron-like 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+ - SnZn++ centre. The concentration of this defect is estimated to be less than 1 µmol mol-1. |
