Abstract

The synthesis of cerium activated yttrium aluminum garnet Y 3Al5O12: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 3Al5O12: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.
