Abstract
We demonstrated the change of shape and crystal phase of LaPO4:Eu3+ nanomaterials by tuning the temperature of heating. The mechanism related to morphology control of LaPO4:Eu nanorods/nanoparticles are proposed and discussed. We describe the "oriented
attachment" growth mechanism for nanorod-to-nanoparticles transformation with increasing the temperature of heating. It is found that the photoluminescence properties of LaPO4:Eu3+ nanostructures are sensitive to the crystal phase and shape. The drastic increase in luminescence
intensity (12 times) and decay time increases from 2.66 to 3.34 ms with changing the shape (nanorod to nanoparticle) and crystal phase (hexagonal to monoclinic phase) for the samples prepared by emulsion based method. Our analysis suggests that the manipulation of the photoluminescence property
can be done by changing the crystal phase of nanomaterials.
