Abstract

The compound HgGa2S4 has been found to fluoresce at room temperature under excitation by ultraviolet-, cathode- or X-rays. The material exhibits two emission bands. If prepared with a surplus of HgS, a yellow emission band, peaking at 5700 Å is present. With a surplus of Ga2S3 a red emission band, peaking at 7000 Å is formed. Activation with copper increases the intensity of the red band markedly and causes a shift to 7300 Å.

    Sometimes, the stoichiometry vacancy causes the unit cell defect which have the intensity properties in common semiconductors. Order vacancy compound (VOCs) as AIIB2XVI adamantine type, have defect chalcopyrite (DC) structure [20,21]. These defects inside of the compounds show the specific properties due to their anisotropy and wide range of band gap energies [21–24].
