Controlled synthesis and luminescence properties of LaPO4:Eu phosphors

► A simple, hydrothermally controlled synthesis of LaPO4 without using surfactants or templates. ► Investigate the effect of experimental conditions on the growth of the LaPO4 nanocrystals. ► Elucidate a possible growth mechanism of hexagonal LaPO4 nanocrystals. ► Investigate the photoluminescence properties of LaPO4:Eu with different morphologies.
