Abstract
ODMR of self-trapped excitons in mixed crystals AgBr x Cl 1- x (\(0{\lesssim}x{\lesssim}0.53\)) has been studied. With the increase of x , excitons become trapped at Ag sites having increasing numbers of Br ions in their coordination shells. For \(0.3{\lesssim}x{\lesssim}0.53\), excitons seem to be characterized as (AgBr 6 ) 5- complexes. These observations are explained by tunneling of excitons to energetically lower sites. Tunneling is, also, capable of explaining the abrupt change of the self-trapped state to the free state of excitons around x ∼0.55 reported by Kanzaki et al.
