摘要：

The synthesis conditions for a brilliant red selenium ultramarine with pigment properties are reported. Structural and electron-microscopic investigations indicate, that these compounds possess the nosean structure with underoccupied Na+ and anionic positions, which contain the colour-determining species. It is concluded by applying various spectroscopic methods that the colour is generated by Se2- radicals. Hydrothermally grown single crystals were pink, with only very small amounts of Se2- being present, which were distinctly spectroscopically but not structurally detectable.
