Sr5(PO4)3Cl:Eu2 + with multiform morphologies and sizes: Hydrothermal synthesis and luminescent properties

• Sr5(PO4)3Cl:Eu2+ with multiform morphologies has been synthesized.
• The morphology is influenced by the phosphate source and surfactant.
• Their optical properties are strongly dependent on their morphologies and sizes.

Sr5(PO4)3Cl:Eu2 + nano/microcrystals with a variety of morphologies, such as nanorod, submicroshperes, nanoparticles, and nanospheres, have been synthesized via a facile hydrothermal route. The effect of phosphate source and surfactant on the morphologies and sizes has been studied. A systematic study on the photoluminescence of Sr5(PO4)3Cl:Eu2 + with different microstructures has shown that the optical properties of these phosphors are strongly dependent on their morphologies and sizes. This synthetic methodology provides a new gateway to other Eu2 + doped luminescent materials.
