Abstract
Hydrogarnet Sr3Al2(OH)12 (SAH) has been obtained from hydrothermal systems with a wide range of pH values under mild conditions. The influence of reaction conditions on the formation of various phases has been considered. The addition of sodium hydroxide can favor the yield of pure SAH phase. Stoichiometric Sr3Al2O6 (SAO) has been prepared from SAH through thermal decomposition over 600 °C for 4 h. SAO can act as a red phosphor host with doping of Eu3+ ions. The Eu3+ ions as activators can be introduced directly under hydrothermal conditions before thermal decomposition.
