Lanthanide ions-doped SrMoO4 microcrystals: Synthesis, characterizations, luminescence, and detection of Fe3+ ions

A facile and green synthetic method for the synthesis of a Ln3+(Eu, Tb)-doped SrMoO4 (SMO) microcrystals were developed using an environment-friendly low temperature hydrothermal method assisting with phenol formaldehyde resin (PFr). The microcrystals show narrow distribution and uniform particle size, and strong red and green emissions from Eu3+ and Tb3+ ions, and it is selectively quenched upon addition Fe3+ ions, thus making the microcrystals as a potential Fe3+ ions sensing material, and the detection limit is nearly micromole level.
