✦ Synopsis
The synthesis of cerium activated yttrium aluminum garnet Y 3 Al 5 O 12 : Ce by the wet-chemical synthesis route is reported. Y-Ce-Al precursors were prepared using the reagent simultaneous addition technique -SimAdd from Y-Al-Ce nitrate mixture and urea and subsequently transformed into phosphor samples. The influence of the thermal synthesis regime and flux on the phosphor quality was investigated in order to obtain Y 3 Al 5 O 12 : Ce fine powders with pure cubic structure and quite good photoluminescent properties. Attempts has been made at establishing a correlation between luminescent properties and morpho-structural parameters of powders.
