Paper Abstract

Deviation from stoichiometry to Ga2S3 excess is shown to be an effective method to obtain mercury thiogallate crystals with strong 670 nm luminescence, photosensitivity at (lambda) < 700 nm and large light-sums storage. The smaller Ga cations are able to create easier antistructural Ga(mu g) defects, to occupy stoichiometric voids, and interstitial sites are supposed to be responsible for the changes.
